Question

A recipe takes 3/4 of salt for 14 servings. We are making the recipe for 28 people. How much salt will we need

Answer 1

14+14 equals 28 ppl so you have to double the recipe 3/4 + 3/4 = 6/4 and then you convert it to a whole fraction

sooo... your answer is 1 1/2

Answer 2

Double 3/4.
Therefore the answer is 6/4 i.e. 1.5 :)
