Question

Michael finished colouring a picture in `7/12` hour. Vaibhav finished colouring the same picture in `3/4` hour. Who worked longer? By what fraction was it longer?

Answer 1

Time taken by Michael = `7/12` hr

Time taken by Vaibhav = `3/4` hr

Converting these fractions into like fractions, we obtain

`3/4 = (3 xx 3)/(4 xx 3) = 9/12`

And `7/12`

Since 9 > 7,

Vaibhav worked longer.

Difference = `9/12 - 7/12 = 2/12 = 1/6` hour
