Question

As an estimation we are told £3 is €4. Convert £73.50 to euros.

Answer 1

€98

Explanation:

£3 = €4

£73.5 = €x

Let the unknown euros be x.

Cross multiply

3 × x = 4 × 73.5

3 × x = 294

Divide both sides by 3.

x = 294/3

x = 98

Answer 2

£73.5 = € 98

Explanation:

Let's use the unitary method

=> £3 = €4

So,

£1 = €4/3

Multiplying both sides by 73.5

£73.5 = € 98
