To subtract fractions, you need a common denominator. In this case, the common denominator is 10.
So, 1/2 becomes 5/10 and 1/10 remains unchanged.
Therefore, the expression 1/2 - 1/10 is equal to 5/10 - 1/10 which is equal to 4/10.
Simplifying this fraction, you get 2/5.
Therefore, 1/2 - 1/10 is equal to 2/5.
