This is a SAT math type of question: What percent of 5 is 9?

Answer 1

You can also use the proportinn method which works for all types of percent problems.

Percent/100 = Is/Of

In thsi problem we don't know the percent (use an x). "Of" is 5 and "Is" is 9. Not necessary to convert result to percent, as the 100 in the denominator does that automatically.

So x/100 = 9/5 v solve by cross-multiplyiing as usual

5x = 900 x = 900/5 = 180%

All percent word problems can be converted to an "Is" "of" format. THen you can just plug the values into the proportion.

Answer 2

In the context of percent problems, "of" indicates the base for comparison, which is the denominator. (In other contexts, "of" can be translated as "multiply".)

Similarly, "is 9" indicates the amount to be compared, which is the numerator.

(amount to be compared) / (base for comparison)

= 9 / 5 = 1.8

To convert to percent, realize that each whole number (1) is composed of 100%. In other words, 1 = 100%.

1.8 * ( 100% / 1 ) = 180%

The SAT tests your understanding of math at a deep level, not the basics. So you need to understand that percents are often greater than 100%.

Answer 3

Let x = percent, "of" means multiply and "is" means equal to.

Now set up an equation so 5x=9.

Solve for x by dividing both sides by 5.

So we have 5x/5 = 9/5

X= 9/5= 180/100 so x is 180%.
