Question

Matt is making cookies. He adds 3/4 cups of sugar to a bowl. He then removes 1/8 cups of sugar. Which of the following best explains the amount of sugar left in the

bowl?
A.3/8 because 3/4-2x(1/8)=3/4-2/8
B.3/8 because 3/4-2x(1/8)=3/4-3/8
C.4/8 because 3/4-2x(1/8)=3/4-2/8
D.4/8 because 3/4-2x(1/8)=3/4-3/8

Answer 1

To find the amount of sugar left in the bowl, subtract the amount of sugar removed from the initial amount of sugar. In this case, 5/8 cups of sugar is left in the bowl.The correct option is: B. 3/8 because \( \frac{3}{4} - 2 \times \frac{1}{8} = \frac{3}{4} - \frac{3}{8} \)

Step-by-step explanation:

To find the amount of sugar left in the bowl, we can subtract the amount of sugar removed from the initial amount of sugar. In this case, Matt added 3/4 cups of sugar and then removed 1/8 cups of sugar. To subtract fractions, the denominators must be the same, so we need to find a common denominator.

The least common multiple of 4 and 8 is 8. Converting 3/4 to have a denominator of 8, we get 6/8. Now we can subtract 1/8 from 6/8: 6/8 - 1/8 = 5/8.The correct option is: B. 3/8 because \( \frac{3}{4} - 2 \times \frac{1}{8} = \frac{3}{4} - \frac{3}{8} \)
