Question

12 is %60 percent of what number?

Answer 1

12 is 60% of 20.

Explanation:

4 is one fifth of 20, or 20%. 8 is two fifths of 20, or 40%. And 12 is three fifths of 20, or 60%. Therefore, 12 is 60% of 20.

Answer 2

There are a couple ways to solve this. One way, and probably the easiest way, is by using proportions.

The two fractions we need to use are 12/x and 60/100 These two fractions are equal, but we don't know what the denominator of the first fraction.

We can find that out by cross multiplying. If our fractions are a/b and c/d we need to multiply a and d then b and c. Somehow, these two products are going to match up.

So, we multiply 12 and 100 to get 1200. Multiplying x and 60, we get 60x.

Since 1200=60x, we just need to divide 1200 by 60 to get x. (That equals 20 btw)

In conclusion 12 is 60% of 20.
