Dear Student
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 she had completed in 11⁄4 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, Renu completed 5/12 part of her home work in 5/4 hours.
Thanks
