Karla is baking a cake for her grandmother’s birthday. The recipe calls for 2/3 cup of sugar. Karla has already added 1/4 cup of sugar to the bowl. How much more sugar does she need to put in to the bowl?
A.
1/7 cups
B.
5/0 cups
C.
5/12 cups
D.
11/12 cups
To find out how much more sugar Karla needs to put in the bowl, we need to subtract the amount of sugar she has already added from the total amount needed.
Total amount needed = 2/3 cup
Amount already added = 1/4 cup
To find the remaining amount, we subtract 1/4 from 2/3:
2/3 - 1/4
To do this, we need to find a common denominator. The least common multiple of 3 and 4 is 12.
We then convert 2/3 to have a denominator of 12:
(2/3) * (4/4) = 8/12
Now we can subtract the fractions:
8/12 - 3/12 = 5/12
Therefore, Karla needs to add an additional 5/12 cups of sugar to the bowl.
The answer is C. 5/12 cups.
