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?
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.
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
