Question

Michael finished colouring a picture in 7/12 hours and Vaibhav finished colouring the same picture
In 3/4 hours . Who worked longer and how much ?​

Answer 1

Answer: Vaibhav took longer by 1/6 hrs or 10 min.

Step-by-step explanation:

7/12 or 3/4

You can simply cross multiply the numerators the denominators of both the fractions to find out the bigger fraction.

7x4 or 12x3

=28 or 36

As 36 is bigger, therefore 3/4 is bigger fraction.

Hence, Vaibhav took more time.

Now, we find the difference by subtracting the bigger fraction from the smaller one-

3/4 -7/12 hrs

= (9-7)/12 hrs

=2/12 hrs

=1/6 hrs

=1/6x60 min

=10 min

Answer 2

• 7-9÷ 12 means that Vaibhav worked 2hrs longer
