Question

George brought a box of fruit that weighed 3 1/2 kilograms. If he gave away 2 5/7 kilograms of fruit to his friends, how many kilograms does he have left?

Answer 1

Data:
brought :
`3 (1)/(2)\:Kg`
gave :
`2 (5)/(7)\:Kg`
how many kilograms does he have left ?



Solving:

`3 (1)/(2) - 2 (5)/(7) = (2*3+1)/(2) - (7*2+5)/(7) = (6+1)/(2) - (14+5)/(7) = (7)/(2) - (19)/(7) = (49-38)/(14) = \boxed{(11)/(14)Kg}`

Answer 2

Left Fruit = Original food - Fruit that he gave to his friend
L.F. = 3 1/2 - 2 5/7
L.F. = 7/2 - 19/7
L.F. = 49 - 38 /14
L.F. = 11 / 14

In short, Your Answer would be 11/14 Kg

Hope this helps!
