Question

From a stick 2y metres long, I cut a piece of length 4y centimetres. What fraction of the original stick remains?

Answer 1

Answer:
`(49)/(50)`

Explanation:

Given

Length of the stick is
`2y\ m`

A piece of
`4y\ cm` is cut

We know, 1 m=100 cm

So,
`2y\ m` in cm is
`200y\ cm`

Remaining length after cut is

`\Rightarrow 200y-4y=196y`

Fraction of length that is left after the cut is

`\Rightarrow (196y)/(200y)\\\\\Rightarrow (49)/(50)`

Thus,
`(49)/(50)` fraction of original stick remains after cut
