Answer:
7 4/5
Explanation:
Step 1. Turn them into improper fractions
6 2/5 = 32/5
(6*5) + 2)
1 4/10 = 14/10
(1*10) + 4)
Step 2. If they don't have the same denominator, you have to find a common multiple (in this case, 10)
14/10 + 64/10
(14/10 × 1/1) + (32/5 × 2/2)
3. Add
14/10 + 64/10 = 78/10
4. Simplify
7 4/5
