Add 3/4 and 2/5.

Explanation:
When adding fractions with different denominators, you first make the bottoms the same. Find a common denominator, here the smallest one that works for 4 and 5 is 20. Convert each fraction to have denominator 20: 3/4 becomes 15/20, and 2/5 becomes 8/20. Now add the tops: 15 + 8 equals 23, so you get 23/20. That fraction is already in simplest form and is an improper fraction, meaning it’s more than one whole. It can also be written as 1 and 3/20 in mixed form. So the sum is 23/20.
