Question

Carrine shared a pizza with her siblings. She gave 1/9 of the pizza to her sister. and 1/3 of the pizza to each of her two brothers. She ate the remaining pizza. What fraction of the pizza did Carrine eat?

Answer 1

2/9

Explanation:

convert thirds to ninths by multiplying top and bottom number in the fraction by the same multiplyer (3×3=9 so the top number has to be multiplied by 3 as well) so 1/3 = 3/9 so 2x brothers had 6/9 in total

then add 1/9 given to sister =7/9 given away

9/9 - 7/9 leaves 2/9
