Question

There are 110 calories per 28.4 grams of crispy rice cereal. Find how many calories are in 42.6 grams of this Cereal

Answer 1

Let x = the number of calories in 42.6 grams of this cereal

 

110   =   x

28.4     42.6

 

Since this is a proportion, you are able to cross-multiply.

28.4x = 110(42.6)

28.4x = 4686

 

Divide both sides by 28.4.

 

x = 165 calories
