Chirstine baked a pumpkin pie. She ate 1/6 of the pie. Her brother ate 1/3 f it ang gave leftovers to his friends. What fraction of the pie did he give to his freinds?

1/2

Step-by-step explanation:

Let the total pie be 2

She ate 1/6

Her brother ate 1/3

If she gave her Friend the remaining, the fraction of the amount her friend collected is expressed as:

1-(1/6+1/3)

= 1-((1+2)/6)

= 1-3/6

= 1 - 1/2

=1/2

Hence the fraction she gave her friend is 1/2
