Joe has eaten 3/5 of pizza. Jane has eaten 1/7 of pizza. how many times more pizza has Joe eaten than Jane
Lana71 [14]

The answer would be 14/5.

First of all, get the denominators to be the same. The LCM is  5 × 7 = 3/5

So  1 /7 × 5/ 5 = 5 /3/5

And  2/ 5 × 7 /7 = 14 /35

Now we have  5 /35  and  14 /35

Then all you have to do is divide Joe's by Jane's to get the answer.

14 /35 ÷ 5 35 =14 /35 × 35/ 5 = 14 /5

Meaning the answer is 14/5.

Hope I could help! :)
