Question

Sam cut a flat wooden board into fourths. He used three of the pieces as backgrounds for posters. He used equal pieces of the leftover board as backgrounds for 5 photos. What fraction of the original board did he use for each photo background? Enter your answer in the boxes.

Answer 1

To answer this question you would start with 1 whole piece and break it into 4 equal pieces. Each piece would be 1/4 of the original.

If you used 3 of these, you are left with 1/4.

Out of the 1/4 leftover, you create 5 equal-sized pieces.

1/4 divided by 5.
1/4 x 1/5 = 1/20 of the original board for each.
