was spent in doing the project work?

Answer 1

Answer:

We must make the denominator same

6/7 ×4/4 =24/28

3/4 ×7/7 = 21/28

24/28 is greater than 21/28

Step-by-step explanation:

Therefote, Gagan spent more hours

Answer 2

Gagan spent more hours than Tanmay by 3/28 hours.

Step-by-step explanation:

We use cross multiplication method to check who spent more time to complete his project =

$\frac{6}{7} \times \frac{3}{4} = 24 > 21$

So, Gagan spent more hours.

Time more spent by Gagan =

$\frac{6}{7} - \frac{3}{4}$

$= \frac{3}{28}$
