Question

24 red marbles is 40% of ____ marbles

Answer 1

HI! The answer to that is 60 marbles.

$\frac{24}{60} = \frac{4}{10}$

Answer 2

40% = .4 because % means hundredths. So 40% = 40/100 = .4

Let x be the total number of marbles.

Then, .4x = 24

  Divide both sides by .4

          x = 60 and 24 is 40% of 60 marbles
