Answer: They are equal to one another.
1/5 is equal to 2/10.
First we must find a common denominator that both 2 and 10 can be divided by. 2 is a number that both are divisible by. So we must divide 2/10 by 2,leaving 1/5. This means that the number are equal to one another. So neither are greater than the other.
I hope this helps & Good Luck <3!!
