Question

Mrs. Lau rolls out 2 3/4 feet of dough to make noodles. If the noodles are 3/8 of an inch wide, how many noodles will she make?

Answer 1

7

Explanation:

2 3/4=2.75

3/8=0.375

2.75/0.375=7.333333

Since Mrs. Lau cannot make 7.333333 noodles, she can only make 7.

Answer 2

• 7 noodles

Explanation:

Divide the full length by the width of each noodle:

• 2 3/4 ÷ 3/8 =
• 11/4 ÷ 3/8 =
• 11/4 × 8/3 =
• 22/3 =
• 7 1/3

The whole part of the quotient is the answer, 7 noodles
