Order least to greatest 3/40, 4/25, 1/10

The answer should be (3/40), (1/10), (4/25).

I found a common denominator for them which is 200 and then times all the numerators and denominators so the denominator was 200, making the fractions go from (3/40),(4/25),(1/10) to (15/200),(32/200),(20/200) then it's easier to put them in order! But make sure to write them in their original value
