Answer 1

Given:

An iron pipe of length 5* 1/ 3  m long was cut into two pieces.

One piece is 3 *1/7  m  long

To find:

What is the length of the other piece?​

Solution:

The length of the iron pipe = $5\frac{1}{3}\: m = \frac{16}{3} \:m$

The length of one of the pieces cut from the iron pipe = $3\frac{1}{7} \:m = \frac{22}{7} \:m$

Therefore,

The length of the other piece is,

= [Length of the iron piece] - [Length of one of the piece]

= $\frac{16}{3} - \frac{22}{7}$

taking L.C.M of the denominators i.e., L.C.M of 3 & 7 is 21

= $\frac{(16\times 7)\:-\:(22\times 3)}{21}$

= $\frac{112\:-\:66}{21}$

= $\frac{46}{21}$

converting into mixed fractions

= $\bold{2\frac{4}{21} \:m}$

Thus, the length of the other piece of the iron pipe is → $\underline{\bold{2\frac{4}{21} \:m}}.$
