A student multiplied two mixed fractions in the following manner: 2 4/7 × 3 1/4 = 6 1/7. What error the student has done?

Solution:

We know tha

2 4/7 × 3 1/4 = 18/7 × 13/4

By further simplification

= (9 × 13)/ (7 × 2)

So we get

= 117/14

= 8 5/14

In the question it is given as

2 4/7 × 3 1/4 = 6 1/7

Therefore, the error the student has made is that mixed fractions are not converted into improper fractions.
