24 is 40% of what number? Use the percent equation.

Answers

Divide 24 by 40%

24 / 0.40 = 60

The answer is 60

Using the percentage equation, 24 ( twenty four ) is 40% ( forty percent ) of 60 ( sixty ).

What is Percentage?

Percentage is simply number or ratio expressed as a fraction of 100.

The perecent equation is expressed as;

Percentage = ( Part / Whole ) × 100%

Given the data in the question;

Percentage = 40%Part = 24Whole = ?

We determine the number, we substitute our given values into the expression above.

Percentage = ( Part / Whole ) × 100%

40% = ( 24 / Whole ) × 100%

40/100 = ( 24 / Whole ) × 100/100

40/100 = 24 / Whole

We cross multiply

40 × Whole = 24 × 100

40 × Whole = 2400

Whole = 2400 / 40

Whole = 60

Therefore, using the percentage equation, 24 ( twenty four ) is 40% ( forty percent ) of 60 ( sixty ).
