Question

A yogurt costs 55 pence . how many yogurts can be bought for 3 pounds

Answer 1

Okay so this is a matter of how many 0.55's go into 3.00

The best way to do this is:
Convert 3.00 to pence
3.00 = 300p

Then keep adding 55p to itself to work out how much 1 yoghurt is, 2 then 3 etc.
1 yoghurt = 55p
2 yoghurts = 110p
3 yoghurts = 165p
4 yoghurts = 220p
5 yoghurts = 275p
6 yoghurts = 330p

Okay, now 330p is 3.30 which is more than 3.00, which means that there isn't enough money for 6, but there is for 5.

EXTENSION:
To work out how much would be left over:
300 - 275 = 25p

Answer 2

we have to see how many times 55 pence fits into 3 Pounds:

3/0.55=?

if we multiply both numbers by 100, so that there are no fractions, we have:

300/55=5 and 25 cents left
(check: 5*55=275)

so the correct answer is 5 yoghurts.
