natta225 [31]

Answer:

D. 6 7/8

Step-by-step explanation:

First, convert 2 3/4 to an improper fraction.

2 times 4 = 8

8+3=11

11/4 ÷2/5

Then, flip the second fraction and change the sign to multiplication.

11/4 × 5/2

Multiply.

11 × 5 = 55

4 × 2 = 6

55/6

Simplify the fraction.

6 7/8

Madison and her sister went to the store together. After the store, Madison walked 2 blocks west to get a coffee and her sister
ladessa [460]

Answer: 5 blocks

Step-by-step explanation:

If they both walked in the same direction, they both will be the same distance from each other.

If Madison went to a coffee shop 2 blocks west from the store, and her sister went from the store they were previously at to her job 7 blocks west, then, since they walked in the same direction, they would only be 5 blocks away.

Hope this helps :)
