how do you convert a percent to a fraction?
Answer:
Step 1: Write down the percent divided by 100 like this: [tex]\frac{percent}{100}[/tex]
Step 2: If the percent is not a whole number, then multiply both top and bottom by 10 for every number after the decimal point. (For example, if there is one number after the decimal, then use 10, if there are two then use 100, etc.)
Step 3: Simplify (or reduce) the fraction
Step-by-step explanation:
Example:
Step 1: Write down:
[tex]\frac{11}{100}[/tex]
Step 2: The percent is a whole number, go straight to step 3.
Step 3: The fraction cannot be simplified further.
Answer:
To convert the percent into a fraction, divide it by 100 and remove the % symbol. Then, multiply the fraction to its lowest term.
For example:
[tex] \sf{12 \: \% \: = \frac{12}{100} = \frac{3}{25} } \: [/tex]
[tex] \sf{65\% \: = \frac{65}{100} = \frac{13}{20} }[/tex]
[tex] \underline{ \sf{some \: facts \: about \: percentage}}[/tex]
[tex] \star[/tex] Percentage are fractions whose denominators are 100
[tex] \star[/tex] A fraction can be expressed as a percentage by converting it into an equivalent fraction with 100 as a denominator.
[tex] \star [/tex] We can convert a fraction to a percent by multiplying it by 100 and the % symbol.
[tex] \star[/tex] A fraction with denominator 100 can be written as a percentage by writing the numerator with the % symbol.
[tex] \star[/tex] To convert a percentage to a decimal , divide it with 100 i.e move the decimal the places to the left.
[tex] \star[/tex] To convert a percentage to a fraction , divide it by 100 and reduce it to the lowest term.

Solve 3x + k= c for x.
O A. x=-*
B. x=3(0 - k)
C.
C + K
3
D. x = 31c+ k)
Answer:
x = c/3 - k/3
Step-by-step explanation:
Solve for x:
k + 3 x = c
Subtract k from both sides:
3 x = c - k
Divide both sides by 3:
Answer: x = c/3 - k/3

2x² + x + 10 = 0 dengan rumus abc
Answer:
a = 2, b = 1 and c = 10
Step-by-step explanation:
The given equation is 2x² + x + 10 = 0 ...(1)
The general form of a quadratic equation is given by :
ax²+bx+c=0 ...(2)
We need to find the values of a,b and c in the given equation.
Comparing equation (1) and (2),
a = 2, b = 1 and c = 10
Solve for x:
- 11x + 32.5 < 82
Answer:
x>-4.5
Step-by-step explanation:
- 11x + 32.5 < 82
Subtract 32.5 from each side
- 11x + 32.5-32.5 < 82-32.5
- 11x < 49.5
Divide each side by -11. remembering to flip the inequality since we are dividing by a negative
-11x/-11 > 49.5/-11
x>-4.5

Miranda wants to join Kick Start Gym and they have two plans she can choose from. Plan A will cost $12 per month plus a $130 joining fee. Plan B does not have a joining fee, but will cost $25 per month. Write and solve an equation to find the number of months for which the cost of each plan is equal.
Answer: 10
Step-by-step explanation:
Cost of any plan = Joining fee + (Per month fee ) × (number of months )
Let x be the number of months for which the cost of each plan is equal.
Cost of plan A = 130 + 12 x
Cost of plan B = 0+ 25x = 25x
According to the question,
[tex]25x = 130+12x\\\\\Rightarrow 25x-12x=130\\\\\Rightarrow\ 13x=130\\\\\Rightarrow\ x=\dfrac{130}{13}\\\\\Rightarrow\ x=10[/tex]
Hence, the number of months for which the cost of each plan is equal is 10.

the perimeter of a rectangle is 28 meters and the length of the base is 8 meters. find the height of the rectangle.
Answer:
6 meters
Step-by-step explanation:
We know that the perimeter of a rectangle is the sum of the length and height doubled, therefore, we can write the following equation:
28 = 2 * (8 + h) where h = height
14 = 8 + h
h = 6 meters

Brand X copier advertises that its copiers run 24% longer between service calls than its competitor. If Brand X copiers run 59,800 copies between services, how many copies would the competitor run?
Answer:
The competitor will run 48,225.81 copies.
Step-by-step explanation:
Brand x copier run 59,800 copies between services
Brand X copiers run 24% longer between service calls than its competitor.
Let x = copies run by the competitor between services
Number of copies the competitor will run is
24% of x + x = 59,800
0.24x + x = 59,800
1.24x = 59,800
x= 59,800 / 1.24
x = 48,225.81
Therefore, the competitor will run 48,225.81 copies.

3. Which of the following does not have a
value that is greater than 0?
a. (-14)
b.
y
C. 0.052
d. -42
Answer:
C. 0.052
Step-by-step explanation:
A and D are negative.
That means that they come before 0 and are therefore smaller than 0.
We do not know the value of B.
C is a positive number, meaning it comes after 0 and is therefore greater than 0.
The sum of two numbers is 77. The greater number is 5 more than the smaller number. Which equation
can be used to solve for the smaller number? (5 points)
1) x(x-5)=77
2) x(x+5)=77
3) x+(x+5)=77
4)x-(x+5)=77
Answer:
3)
Step-by-step explanation:
X is the smaller number and when we add 5 to the smaller number we get the greater number therefore summing up both the smaller and greater number gives a total of 77 as the question gives guidelines
17. The length of a rectangle is 3 inches greater than its width. The perimeter is 28 inches.
Find the dimensions of the rectangle.
Answer:
[tex] \boxed{ \bold{ \sf{ width \: of \: a \: rectangle = 5.5 \: inches}}}[/tex]
[tex] \boxed{ \bold{ \sf{length \: of \: a \: rectangle =8.5 \ \: \: inches}}}[/tex]
Step-by-step explanation:
Let the width of a rectangle be 'w'
Length of a rectangle = w + 3
Perimeter of a rectangle = 28 inches
To find : dimensions of the rectangle ( length and width )
Finding the width of a rectangle ( w )
[tex] \boxed{ \sf{perimeter \: of \: a \: rectangle = 2(l + w)}}[/tex]
[tex] \dashrightarrow{ \sf{28 = 2(w + 3 + w)}}[/tex]
[tex] \dashrightarrow{ \sf{28 = 2(2w + 3)}}[/tex]
[tex] \dashrightarrow{ \sf{28 = 4w + 6}}[/tex]
[tex] \dashrightarrow{ \sf{4w + 6 = 28}}[/tex]
[tex] \dashrightarrow{ \sf{4w = 28 - 6}}[/tex]
[tex] \dashrightarrow{ \sf{4w = 22}}[/tex]
[tex] \dashrightarrow{ \sf{ \frac{4w}{4} = \frac{22}{4} }}[/tex]
[tex] \dashrightarrow{ \sf{w = 5.5 \: inches}}[/tex]
Width of a rectangle = 5.5 inches
Now, replacing / substituting the value of w in order to find the length of a rectangle
[tex] \sf{ length = 3 + w}[/tex]
[tex] \dashrightarrow{ \sf{length = 3 + 5.5}}[/tex]
[tex] \dashrightarrow{ \sf{length = 8.5 \: \: inches}}[/tex]
Length of a rectangle = 8.5 inches

so 5/10+4/10=9/10
Together they will have 9/10 part a dollar.
What is proportion ?
A proportion is an equation based on the equality of two ratios.
Here, Carmen has 4/10 of a dollar and Try says he has 50/100 part of a dollar, now to calculate the fraction of dollar together they will be having will be the sum of Carmen and Troy part of dollar :
[tex]\begin{aligned}\frac{4}{10}+\frac{50}{100}&=\frac{4}{10}+\frac{5}{10}\\&=\frac{9}{10}\end{aligned}[/tex]
