Question

When babies are born, their lengths are recorded. Maddy is 18 1/2 inches. Her twin Alex is 10 3/4 inches. What is the difference in length between Maddy and Alex?

1) 7 3/4 inches
2) 7 1/4 inches
3) 8 1/4 inches
4) 8 3/4 inches

Answer 1

To find the difference in length between Maddy and Alex, subtract the length of Alex from the length of Maddy. The difference in length between Maddy and Alex is 6 3/4 inches.

Step-by-step explanation:

To find the difference in length between Maddy and Alex, we subtract the length of Alex from the length of Maddy.

Maddy's length is 18 1/2 inches, which can be written as 18 + 1/2 inches.

Alex's length is 10 3/4 inches, which can be written as 10 + 3/4 inches.

Now, subtracting the lengths, we get:

(18 + 1/2) - (10 + 3/4) = 17.5 - 10.75 = 6.75 inches.

Therefore, the difference in length between Maddy and Alex is 6 3/4 inches.
