Question 1167232: Pilar bought 8 3/4 kg of fruit. She put 5/8 of them were girls, how many are boys?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! the total amount of fruit is 8 and 3/4 kilograms.
5/8 of the fruit is given to the girls.
the rest is given to the boys.
the girls get 5/8 * (8 and 3/4) kilograms of the fruit.
the boys get 3/8 * (8 and 3/4) kilograms of the fruit.
that's because all of the fruit is 8/8 of the fruit.
since 8/8 is equal to 1, then:
8/8 * (8 and 3/4) = 1 * (8 and 3/4) = 8 and 3/4 which is all of the fruit.
if the girls get 5/8 of the fruit, then 8/8 minus 5/8 = 3/8.
that's what's left for the boys.
so, .....
the girls get 5/8 * (8 and 3/4) kilograms of fruit.
the boys get 3/8 * (8 and 3/4) kilograms of fruit.
8 and 3/4 kilograms of fruit is equal to 35/4 kilograms of fruit.
5/8 * 35/4 = 175/32 = 5 and 15/32 kilograms of fruit.
3/8 * 35/4 = 105/32 = 3 and 9/32 kilograms of fruit.
the girls get 5 and 15/32 kilograms of fruit.
the boys get 3 and 9/32 kilograms of fruit.
