Jessica is baking a cake. The recipe says that she has to mix 96 grams of sugar into 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:
She needs 1/4 cup more
Step-by-step 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
