Question

James uses 1/2 of a cup of sugar in his cookies, and Jade uses 3/4 of a cup of sugar in her cookies. Noel takes the sum of the two amounts of sugar and divides it into two equal portions, planning to use only one portion of it in his cookies. How much sugar does Noel use in his cookies?

A. 3/4 of a cup
B. 5/8 of a cup
C. 5/16 of a cup
D. 1/2 of a cup

Answer 1

5/8 of a cup

Explanation:

What you do is you add 1/2 and 3/4 together.

1/2+3/4=5/4.

Noel used half of 5/4 so you would multiply it by 1/2

5/4*1/2=5/8 is your answer.

Answer 2

B. 5/8 of a cup

Explanation:

1/2 + 3/4

find common denominator

1/2 · 2/2 = 2/4

add fractions

2/4 + 3/4 = 5/4

multiply by 1/2

5/4 · 1/2 = 5/8 c.
