Question

Paula has 24 stamps in her collection. Among her stamps, 1/3 have pictures of animals, 3/4 of those have stamps have pictures of birds. How many stamps have pictures of birds on them?

Answer 1

24/3 = 8 stamps with pictures of animals, 8 x 3/4 = 6 stamps with birds on them. If it helps 8 has a denominator of 1 so you just multiply the top and the bottom of the fractions. 8x3=24 and you divide that by 4x1

Answer 2

First we need to find 1/3 of 24. When you see "of" replace it with "×".

1/3 of 24 =
1/3 × 24 =
24/ 3 = 8

So 8 stamps are animals. Now we find 3/4 of 8 to find out how many have birds.

3/4 of 8 =
3/4 × 8 =
24/4 = 6

6 have birds
