Question

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

Answer 1

Answer:

VAIBHAV WORKED LONGER

Step-by-step explanation:

Let's compare the fractions and decide which one is larger.

Let's compare the fractions and decide which one is larger.Time is taken by Michael = 7/12 hour

Let's compare the fractions and decide which one is larger.Time is taken by Michael = 7/12 hourTime is taken by Vaibhav = 3/4 hour

Let's compare the fractions and decide which one is larger.Time is taken by Michael = 7/12 hourTime is taken by Vaibhav = 3/4 hour= (3×3) / (4×3) (converting into like fractions)

Let's compare the fractions and decide which one is larger.Time is taken by Michael = 7/12 hourTime is taken by Vaibhav = 3/4 hour= (3×3) / (4×3) (converting into like fractions)= 9/12 hour

Let's compare the fractions and decide which one is larger.Time is taken by Michael = 7/12 hourTime is taken by Vaibhav = 3/4 hour= (3×3) / (4×3) (converting into like fractions)= 9/12 hourSince, 9/12 > 7/12

Let's compare the fractions and decide which one is larger.Time is taken by Michael = 7/12 hourTime is taken by Vaibhav = 3/4 hour= (3×3) / (4×3) (converting into like fractions)= 9/12 hourSince, 9/12 > 7/12Therefore, Vaibhav worked for longer.

Let's compare the fractions and decide which one is larger.Time is taken by Michael = 7/12 hourTime is taken by Vaibhav = 3/4 hour= (3×3) / (4×3) (converting into like fractions)= 9/12 hourSince, 9/12 > 7/12Therefore, Vaibhav worked for longer.Difference = 9/12 − 7/12

Let's compare the fractions and decide which one is larger.Time is taken by Michael = 7/12 hourTime is taken by Vaibhav = 3/4 hour= (3×3) / (4×3) (converting into like fractions)= 9/12 hourSince, 9/12 > 7/12Therefore, Vaibhav worked for longer.Difference = 9/12 − 7/12= 2/12

Let's compare the fractions and decide which one is larger.Time is taken by Michael = 7/12 hourTime is taken by Vaibhav = 3/4 hour= (3×3) / (4×3) (converting into like fractions)= 9/12 hourSince, 9/12 > 7/12Therefore, Vaibhav worked for longer.Difference = 9/12 − 7/12= 2/12= 1/6 hour

Let's compare the fractions and decide which one is larger.Time is taken by Michael = 7/12 hourTime is taken by Vaibhav = 3/4 hour= (3×3) / (4×3) (converting into like fractions)= 9/12 hourSince, 9/12 > 7/12Therefore, Vaibhav worked for longer.Difference = 9/12 − 7/12= 2/12= 1/6 hourThus, Vaibhav took 1/6 hour more than Michael.

Answer 2

Step-by-step explanation:

Michael finished colouring a

picture in 7

12 hours

Vaibhav finished colouring a

picture in 3

4 hours

LCM of 7 and 3 is 7 -9

12 4 12 12

7 - 9 = 2 = 2×1= 2 = 1 hours

12 12 12 2×6=12 6
