Question

find the cost of 3hole2upon5 metres of cloth at 63 hole3upon4 per metre

Answer 1

Given the length of the cloth and the rate. So multiply them.

$rate = 63\frac {3}{4} /m = \frac{252}{4}\\length = 3\frac {2}{5}=\frac{17}{5} m\\\\cost = \frac{255*17}{4*5}= \frac {867}{20}=43\frac{7}{20}$
Ok.
