Question

Which problem would you use the following proportion to solve for?

Answer 1

Answer: C. Twenty-four is 40% of what number

Explanation:

Let the answer in each question is x,

Then in A)  What is 40% of 24

$\frac{24\times 40}{100} = x$

$\frac{40}{100} =\frac{x}{24}$

In B) What percent is 24 of 40,

$\frac{24\times x}{100} = 40$

$\frac{40}{100} = \frac{x}{24}$

In C) Twenty-four is 40% of what number

$\frac{x\times 40}{100} = 24$

$\frac{40}{100} = \frac{24}{x}$

In D)  Forty percent of 24 is what number,

$\frac{40\times 24}{100} = x$

$\frac{40}{100} =\frac{x}{24}$

Thus, in problem C the given expression will use.
