Question

arrange the following increasing order.
3/5,4/10,7/15,9/10

Answer 1

answer is 4/10,7/15 ,3/5,9/10

Answer 2

First take LCM of all these number.

LCM of 5, 10 & 15 is 30.

Now,
3/5 = 18/30
4/10 = 12/30
7/15 = 14/30
9/10 = 27/30

Now all the number has same denominator so the number whose numerator is less is smaller than others so increasing order of this number is:-

4/10 < 7/15 < 3/5 < 9/10

Hope it helps.
