The question

Question: work out −5/8 − 1/8.

−58 − 18

1 Take away the tops

The bottoms are the same, so the pieces are the same size.

We take away the tops.

The bottom stays 8, because the size of the pieces does not change.

= −5 − 18

−5 minus 1 is −6.

= −68

2 Simplify

Both 6 and 8 can be divided by 2.

That makes it simpler.

= −6 ÷ 28 ÷ 2

So it is −3/4.

= −34

Can we make it simpler?

No number goes into both 3 and 4, except 1.

So it stays like this.
