Many thanks to all.........
Life would have been easier had be done more fractions at school. My maths teacher was a great believer in moving forward with the times. In the future (computers and all that) fractions will become obsolete he'd say. Decimals were the way forward. Well thats fine mit calculator but when faced with dividing a small number with a large one it becomes a little more difficult. Such as 40 / 120 to give a nought point something?
I'll brush up on my fractions..
