Question

The length of one piece of string is 1/5m. What will be the total length of 4 such pieces of string?

Answer 1

Answer:
`(4)/(5)\ m`

Explanation:

Given

The length of one piece of string is
`(1)/(5)\ m`

So, the length of 4 pieces is the addition of four-piece length.

`\Rightarrow L=(1)/(5)+(1)/(5)+(1)/(5)+(1)/(5)\\\\\Rightarrow L=4* (1)/(5)\\\\\Rightarrow L=(4)/(5)\ m`
