Answer 1

Given :

Renu completed 2/3 part of her homework in 2hrs

To find :

How much part of her homework had she completed 1¼ hours

Solution :

homework done in 2 hours = ⅔ part

homework done in for 1 hour = ⅔ ÷ 2

= ⅓ part

so,

homework done in 2 hours = ⅔

homework done in 1 hour = ⅓

homework done in 1¼ hour = ⅓ x 1¼

= 5/12 part

=> option 3 is right
