Question

The table shows the portion of some common materials that are recycled.

Material	Recycled
Paper	`5/11`
Aluminium cans	`5/8`
Glass	`2/5`
Scrap	`3/4`

Which items have a recycled amount less than `1/2`?

Answer 1

Similarly, `5/8` is greater than `1/2 (= 4/8)`

Also, `2/5 = (2 xx 2)/(5 xx 2) = 4/10 < 1/2 (= 5/10)`

And `3/4 > 1/2 (= 2/4)`

So, the quantity of paper and glass recycled is less than `1/2`.
