To add fractions, find a common denominator. In this case 20. So convert each fraction to the equivalent fraction with 20 as the denominator, then add the numerators. So 4 x 5 = 20, so for the 2/5, multiply numerator by 4 --> 8/20. And for 3/4, multiply by 5 --> 15/20. Now add: 15 + 8 = 23, so it's 23/20, or 1 3/20.
