1.	Renu completed 2/3 part of her home work in 2 hours. How much part of her home work had she completed in 1¼ hours?
Answer» From the question it is given that, Renu completed 2/3 part of her home work in 2 hours. Let us assume total part of homework be ‘P’. Then, 2/3 of P = 2 2/3 × P = 2 By cross multiplication we get, P = 2 × 3/2 P = 3 home work So, part of her home work had she completed in 1¼ hours i.e. 5/4 hours Let us assume part of home work 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, Reenu completed 5/12 part of her home work in 5/4 hours.

Answer»

From the question it is given that,

Renu completed 2/3 part of her home work in 2 hours.

Let us assume total part of homework be ‘P’.

Then,

2/3 of P = 2

2/3 × P = 2

By cross multiplication we get,

P = 2 × 3/2

P = 3 home work

So, part of her home work had she completed in 1¼ hours i.e. 5/4 hours

Let us assume part of home work 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, Reenu completed 5/12 part of her home work in 5/4 hours.
