The ratio of g to kcal would be the same in 71g
100/360 = 71/x
100x = 25560
x = 255.6

This is where the cross multiplying comes in.
100grams - 360 kcal
71 grams - x kcal
x kcal = (360 x 71)/100
x kcal = 255.6
Hope it helped:)

Cross multiply. 100g/360kcal = 71g/x
So, 100g(X)=360kcal(71g)
100g(X)=25560
X=25560/100
X=255.60 kcal

360 divided by 100 = 3.6

Just put 71/100 to get 71%, or 0.71.
.71 X 360 = 255.6
