Question

Irene bought 5 3/11 m of cloth. Molly bought 1/2 m less than Irene.

A. How many metres of cloth did Molly buy?
B. How many metres of cloth did they buy altogether?

Answer 1

A. 4 17/22

B. 10 1/22

Explanation:

A) First we would need to find a common denominator

The LCM of 11 and 2 is 22

Now, we can change the denominators

5 6/22 - 11/22 is hard to do, so we can turn 5 6/22 to 4 28/22

4 28/22 - 11/22 = 4 17/22

B) 4 17/22 + 5 6/22 = 9 23/22 = 10 1/22

Hope this helps :)
