Question

From a wire `21/2` metre long, Samir cut off `5` pieces of `5/4` metre each. What length of wire was left?

Answer 1

`8.5/2=17/4=4 1/4` metres of wire

Explanation:

I think Samir is starting with `21/2` metres of wire (if I'm reading the question correctly).

He then cuts off 5 pieces, each of which is `5/4` of a metre. The total wire he cut off then, is:

`5xx5/4=25/4=12.5/2` of wire.

The amount of wire left is:

`21/2-12.5/2=8.5/2` metres of wire. This equates to:

`8.5/2=17/4=4 1/4` metres of wire
