Answer:
2/5
Step-by-step explanation:
The original answer was 4/10, but as a reduced fraction, it is 2/5.
Version of how I got it:
5 and 2 have 10 in common, so that is the denominator
1 and 1 have 1 in common. Keep change and flip, to turn this into a 4. this rule applies because 1 + 1 = 2, and 2 x 2 = 4.
finally...
4/10 -- 2/5
hope this helps!
