Question

Jessica is baking a cake. the recipe says that she has to mix 96 grams of sugar to the flour. jessica knows that 1 cup of this particular sugar has a mass of 128 grams. she added one over two of a cup of sugar to the flour. should jessica add more sugar to make the exact recipe, or did she go over and by what amount?

Answer 1

She needs 1/4 cup more

Explanation:

1 over 2 = 1/2 = 0.5

1 cup = 128

So, 1/2 cup = 128*0.5 = 64 grams

Since she needs 96, she will need to add more

96-64 = 32

She will need to add 32 grams of sugar

32/128 =0.25

Therefore, she needs 1/4 cup more

Answer 2

Using her half cup, Jessica added 64 grams of sugar to her mixture. She needs to add 32 grams of sugar to have the right amount.
