Question

John finished coloring a picture in 7/12. Ritu finished coloring the same picture in 3/4hrs. Who worked longer ? By what fraction was it longer ?

Answer 1

Answer:

Step-by-step explanation:

me taken by John = 7/12 hour

Time taken by Ritu = 3/4 hour

Changing the fractions into like fractions, we get

7/12, 3/4

7/12, (3 × 3) ÷ (4 × 3)

7/12, 9/12

Since, 9/12 > 7/12, Ritu worked longer.

Difference = 9/12 – 7/12 = (9 – 7) ÷ 12 = 2/12 = 1/6 hours longer

Answer 2

Answer:

Ritu worked longer than John by 2/12

Step-by-step explanation:

Firstly, We will take the LCM of 12 and 4 and that is 12

So according to it, 7/12=7/12 and 3/4=9/12

From there we get that Ritu had taken more time than John

And the difference is 9/12-7/12 = 2/12(1/6 in standard form)
