Question

1. A studies for 7/4 hours and B studies for 7/5. Who studies for more time?
​

Answer 1

Answer:

A studied for 1 hour and 45 mins

B studied for 1 hour and 24 mins

hence, A studied for more time than B

Step-by-step explanation:

A studies for 7/4 hours which is:

7/4=1.75 hours which is:

0.75×60=45 mins

So A studied for 1 hour and 45 mins

B studies for 7/5 hours which is:

7/5=1.4 hours which is

0.4×60=24 mins

So B studied for 1 hour and 24 mins

So we can see that A studied for more time than B

Answer 2

Answer:

We have Given that,

      A studies for 7/4 hours and B studies for 7/5 hours

• Now 7/4 - 7/5 = 7/20 ( which is positive )
• now,  7/5 - 7/4 = -7/20 ( Which is Negative )

so, from above calculation we find that,

• 7/4 > 7/5
• so A studied more time than B .(Ans.)

Alternative method :

• 7/4 hrs =  7/4  * 60 min = 105 minutes
• 7/5 hrs = 7/5 *  60 min = 84 minutes

• now,     105 minutes > 84 minutes

Therefore,  A studied more than B
