Question

Ube had made a banana cream pie. His brother he 1/3 of a pie and his sister had 2/5 of the pie how much less did his brother eat than his sister

Answer 1

Find the LCD (least common denominator)
15 in this case
Convert to have 15 as denominators

1/3 = 5/15
2/5 = 6/15

Subtract

(6/15) - (5/15)
1/15

He had 1/15 less
