Question

A piece of wire `7/8` metre long broke into two pieces. One piece was `1/4` metres long. How long is the other piece?

Answer 1

Total length of wire = `7/8` metre

Length of one piece of wire = `1/4` metre

Length of other pieces of wire = Length of the original wire and this one piece of wire

= `7/8 - 1/4`

= `[(7 xx 1) - (1 xx 2)]/8`

= `((7 - 2))/8`

= `5/8`

∴ Length of the other piece of wire = `5/8` metre
