Question

The cost of 3¼ metres of cloth is Rs 78. Find the rate per metre. ​

Answer 1

Step-by-step explanation:

First

• converting mixed fraction into improper fraction.

$3 \frac{1}{4} = \frac{3 \times 4 + 1}{4} = \frac{13}{4} metre$

Now

$if \: cost \: of \: \frac{13}{4} metre \: cloth \\ = ₹ \: 78 \\ so \: the \: cost \: of \: 1metre \: cloth \\ = \frac{78}{ \frac{13}{4} } = \frac{78 \times 4}{13} = 6 \times 4 \\ = ₹ \: 24.$

Hope it helps
