Renu completed23part of her homework in 2 hours. How much part of her homework had shecompleted in 11⁄4 hours?

Answer»

Answer:

5/4

Step-by-step explanation:

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
