Question

A recipe requires sugar, flour and cocoa in the ratio 5:4:1

If the total weight of the mixture is 550g what weight of each ingredient is used

Answer 1

Let x be the amount of cocoa you use in the recipe.

then 4x is the amount of flour used, and 5x is the amount sugar used.

x+4x+5x= 550g
10x=550g
x=55g

So, you use 55g of cocoa, 220g of flour, and 275g of sugar.

hope this helps! :)
