    You need to convert the fractions so they have the same denominator (bottom number) so start by finding a common factor.

    As 5 is a factor of 10, we can make that first fraction into 10ths. So to get 10 as the denominator we have to multiply the 5 by 2. We can't just multiply the bottom half of the fraction though, so also have to multiply the numerator by 2 as well. So we end up with 1 8/10 + 3/10
