How do you write a ratio as a percent

Answers

Answer 1

Answer: A ratio is pretty much a fraction

Divide the numerator and denominator. You may or may not get a decimal. Move the decimal point over too the right two place values. You will then get a percentage. If it is a whole number, add two zeros behind and you'll get your percentage.

For example:

10:2 is my ratio

10:2 is the same as 10/2 = 5

5 is the same as 5.00

move the decimal point to the right two place values

5.00 = 500%

hope this helps

Answer 2

Answer: To write a fraction as a percent, we can convert it to an equivalent fraction with a denominator of 100. Another way to write a fraction as a percent is to divide its numerator by its denominator, then convert the resulting decimal to a percent.

36 is 12 percent of what number?

Answers

1. We assume, that the number 12 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 12, so we can write it down as 100%=12.
4. We know, that x% equals 36 of the output value, so we can write it down as x%=36.
5. Now we have two simple equations:
1) 100%=12
2) x%=36
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=12/36
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 36 is what percent of 12

100%/x%=12/36
(100/x)*x=(12/36)*x - we multiply both sides of the equation by x
100=0.333333333333*x - we divide both sides of the equation by (0.333333333333) to get x
100/0.333333333333=x
300=x
x=300

now we have:
36 is 300% of 12

dear, you substitute the number .. example question number 12. it says there x=2 .. so 24x is 24 times 2 = 48 .. then you divide by 6.. 48÷6 = 8 .

Estimate then record the product $53x4

Answers

the answer is 212 you can estimate the answer to be 200

you do 53 times 4 and you get 212 because when you estimate it's 212.
