Philip takes 2 3/5 hours to clean his room. Amy takes 2 5/8 to clean her room. Who took less time to clean up their room ?

Question

How to solve

Answer 1

Hi, Brandie.

 

You need to figure out which number is larger, 2 3/5 or 2 5/8

 

To compare fractions you need a common denominator.

 

3/5  and 5/8 can both have equivalent fractions with a denominator of 40.

 

3/5 x 8/8 = 24/40        and      5/8 x 5/5 = 25/40

 

So, now you can compare 24/40 and 25/40 and see that 25/40 is greater, so 5/8 is greater.

Therefore, Philip took less time to clean his room.
