How do you simplify 10 over 35?

Answer 1

10

---

35

First, you look for any number that divides into both 10 and 35. I like to break the numbers into prime factors:

10 = 5 x 2

35 = 5 x 7

In this case, they have a 5 in common. So break it out on the top and on the bottom (ha ha, bottom)

5 x 2

------

5 x 7

Now you can cross out the two 5s, and that leaves you with the reduced fraction 2/7.
