Question

Jermaine fills his water bottle 5/6 of the way to bring to tennis practice. He drinks 3/5of the water he brought with him. How much of his bottle did Jermaine drink?

Answer 1

7/30

1) To find out that, we need to subtract 3/5 from 5/6

2) Since the denominators are not the same, then we have to proceed with taking the LCM of (6,5) decomposing it by prime factors.

2.2) Now with the new denominator: 30 we can write out:

`(30\colon6*5))/(30)-((30\colon5*3))/(30)=(25)/(30)-(18)/(30)=(7)/(30)`

Then Jermaine drank 7/30 of the water
