Question

Marcus needs 3 1/10 m of blue fabric and 1 1/5 m of yellow fabric to make his costume

How much more blue fabric than yellow fabric does Marcus need?

Express your answer as a mixed number in simplest form

Answer 1

Turn both into decimals or fractions with a common denominator: 3.1 OR 3 1/10 and 1.2 OR 1 2/10

Now you need to subtract : 3 1/10 - 1 2/10 = 1 9/10 OR 1.9

In mixed number form : 1 9/10
