Ali bought 8 pears and 6 mangoes.

A mango costs 4 times as much as a pear.

If 2 pears and 1 mango cost £6.60, how much did Ali pay altogether?

Concept 1: Division as sharing equally

- Cost of mango is 4 times the cost of a pear, hence, both fruits do not cost the same.
- As both fruits do not cost the same, it is not right to use £6.60 ÷ 3 (2 pears + 1 mango).

Concept 2: Multiplication

- A mango costs 4 times as much as a pear

Concept 3: Grouping

- 2 pears and 1 mango cost £6.60

6 units → £6.60

1 unit → £6.60 ÷ 6

= £1.10 (Cost of 1 pear)

4 units → 4 x £1.10

= £4.40 (Cost of 1 mango)

- 8 pears 6 mangoes cost ?

1 unit → £6.60 ÷ 6

= £1.10 (Cost of 1 pear)

8 units → 8 x £1.10

= £8.80 (Cost of 8 pears)

24 units → 24 x £1.10

= £26.40 (Cost of 6 mangoes)

Total cost of 8 pears and 6 mangoes

= £8.80 + £26.40

= £35.20

Ali paid £35.20 altogether.
