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

1/2 of 128 is 64, so she added 64 grams of sugar, which means she still needs to add more sugar. 96 - 64 is 32, so she still needs to add 32 grams of sugar. Hope this helps!
