Question

On a math test, Rosie answered 36 questions correctly, which was 72%. how many questions were on the test?

Answer 1

50

Explanation:

What I did first is I converted 72% into a decimal (I work better with decimals), giving me 0.72. Then I solved the equation 36/0.72=x.

x = 50

Answer 2

• 50 questions

Explanation:

Let the number of questions be x.

We have:

• 72% of x is 36.

Build an equation and solve for x:

• 0.72x = 36
• x = 36/0.72
• x = 50
