Yesterday I bought a strip of multi-coloured cloth. One third and one quarter of it is black, and the other 8 metres are red. How long is the strip?
If you have not tried to solve it, have a go now. For everyone else, the answer is after the break.
If x is the length of the cloth, then
x/3 + x/4 + 8 = x
4x + 3x + 96= 12x
and thus x=19.2 m
Did you solve it? Any other answers?
