Question

48/80 In simplist form ?

Answer 1

3/5

Answer 2

3/5

Answer 3

You can get this by finding a common factor. You can do that several times if you need to to make it easier.

For example, we can divide num/denominator by 2, and you get:

24/40

Then we can divide by 2 again, and you get:

12/20

Then we can divide by two again, and you get:

6 / 10

Then one more time, you get:

3 / 5

The other option is to notice common factors that are greater than 2 or 3. So we could just have divided by 16 in this case and gone straight from 48/80 to 3/5.

Answer 4

The important thing is that you stop at 3 / 5 because there is no longer a number that divides evenly into both the top and the bottom (in this case, there is no number that divides evenly into either of them, as they are prime).
