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?

Respuesta :

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!

Data:
brought : [tex]3 \frac{1}{2}\:Kg[/tex]
gave :  [tex]2 \frac{5}{7}\:Kg[/tex]
how many kilograms does he have left ?



Solving:
[tex]3 \frac{1}{2} - 2 \frac{5}{7} = \frac{2*3+1}{2} - \frac{7*2+5}{7} = \frac{6+1}{2} - \frac{14+5}{7} = \frac{7}{2} - \frac{19}{7} = \frac{49-38}{14} = \boxed{\frac{11}{14}Kg}[/tex]
