Question

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

Answer 1

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!

Answer 2

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!
