Compare 5/4 and 9/10 describe two methods you could use to compare the fractions

Hi there!

One way of comparing fractions is making them into decimals.
The second way is making the denominator equal.

First way
5/4 = 1.25
9/10 = 0.9
1.25 > 0.9
So we know that 5/4 is bigger than 9/10.

Second way
the greatest common multiple of 4 and 10 is 20. So make those two fraction's denominator to 20.
5/4 --> 25/20
9/10 --> 18/20
25/20 > 18/20

So 5/4 is bigger than 9/10.
Hope this helped!

Hi there!

To compare fractions, we can find a common denominator and see whether the numerators are greater or less than each other.

To find a common demoninator, we need to multiply the two denominators together.

4 × 10 = 40

5 × 10 = 50
9 × 4 = 36

50 > 36

Hope this helps!
