Question

An electrician has 3 7/10 cm of wire. He needs only 2 5/8 cm

of wire for a job. How much wire does he need to cut?

Answer 1

The answer can either be 2 5/8 cm in terms of grammar but because it is a mathematics question you will have to subtract the fractions giving us 1 3/40 cm

Explanation:

3 7/10 - 2 5/8

subtract the whole numbers and find the LCM of the fractions which is 40

=1 (( 28-25)/40)

=1 3/40cm
