Well you would have to make the bottom number equal, so the lcm (least common multiple) of 5 and 8 is 40. Which means for the first you have to multiply 5 and 8 both by five to get 25/40. Then multiply 2 and 5 both by 8 so 16/40 then add. So 25/40 + 16/40 = 41/40.

So the answer is 41/40, which reduced ia 1 and 1/40.

Hope that helps!

To add fractions we have to find a common denominator and then add. To find the common denominator of the fractions we can multiply the denominators together to get 40.

Multiply 5/8 × 5/5 = 25/40
Multiply 2/5 × 8/8 = 16/40

Now add the fractions

25/40 + 16/40 = 41/40 or 1 1/40
