Question

a blouse require 1 1/4 m of cloth, how many blouses can be made from 21 m of cloth?

Answer 1

Cloth required for 1 blouse = 1 1/4 = 5/4 m

Cloth available = 21 m

No. of blouse can be made = 21/(5/4) = 21*4 / 5 = 84/5 = 16.8

Answer 2

Answer:

16 blouses can be made from 21 m of cloth.

Step-by-step explanation:

No. of blouse cam be made from $1 \frac{1}{4}$ i.e. $\frac{5}{4}$m of cloth = 1

No. of blouse cam be made from 1 m of cloth = $\frac{1}{\frac{5}{4}}$

                                                                            = $\frac{4}{5}$

No. of blouse cam be made from 21 m of cloth = $\frac{4}{5} \times 21$

                                                                              = $16.8$

So, 16 blouses can be made from 21 m of cloth.

Hence 16 blouses can be made from 21 m of cloth.
