Question

Renu completed 2/3 part of her homework in 2hrs. How much part of her homework had she completed 1 1/4 hours? I need proper solution..​

Answer 1

Step-by-step explanation:

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.
