Answer: 1/5 is equal to 2/10
Step-by-step explanation:
In order to find if the two fractions are equal, less than, or greater than. We have to find the LCD (Least Common Denominator)
In order to find the LCD we have to find the multiples. The multiples of 5 are: 5, 10, 15, 20, and 25. While the multiples for 10 are: 10, 20, 30, 40, 50.
The Least common denominator is: 10.
2/10 stays the same while 1/5 does not.
1 x 2 = 2
---------------
2 x 5 = 10
1/5 turns into 2/10.
Compare 2/10 to 2/10 (1/5)
You can see the are both equal.
; otherwise 
is undefined as long as we're only looking for real solutions.
