Question

Renu completed `2/3` part of her home work in 2 hours. How much part of her home work had she completed in `1 1/4` hours?

Answer 1

From the question, it is given that,

Renu completed the `2/3` part of her homework in 2 hours.

Let us assume the total part of the homework is ‘P’.

Then,

`2/3` of P = 2

`2/3` × P = 2

By cross multiplication we get,

P = 2 × `3/2`

P = 3 homework

So, part of her homework she had completed in `1 1/4` hours i.e. `5/4` hours

Let us assume part of the homework she had completed in `5/4` hours be = Q

Then,

Q of 3 = `5/4`

Q × 3 = `5/4`

By cross multiplication we get,

Q = `5/4 × 1/3`

Q = `5/12`

Therefore, Renu completed the `5/12` part of her homework in `5/4` hours.
