3 and 20 have no common factor other than 1

Answer 8

Then I have a bunch of repeting deccimals I have no clue what to do with..

Answer 9

3/20 is equal to .15

Answer 10

It has to do with the place value of the last number to the right of the decimal. Any number to the left of the decimal is a whole number, but to the right of the decimal, it is less then 1.
Now look at your number...7.15....the 7 is the whole number...now look at the last number, the 5, what place value is this in ? It is in the 100ths place, therefore, put it over 100.
7 15/100.....which reduces to 7 3/20 or if you need it into an improper fraction, it is 143/20

Answer 11

that would be 5/9

Answer 12

I'm not sure how to put this into a fraction like he steps to doing it?

Answer 13

i dont know how to explain it, i just know how to do it

Answer 14

7.15....the last number, the 5, is in the 100dths place....so put your whole number 7 and then make your fraction 15/100....now the 15/100 reduces to 3/20.
So your answer is 7 3/20.

Example :
3.012...the 3 is your whole number....now look at your last number, the 2, it is in the 1000dths place.....so we now have 3 12/1000....which reduces,but I am too lazy to do that.

It all has to do with place value of the last number to the right of the decimal
