C

Step-by-step explanation:

3/4 + 6/10

Find a common denominator and find what you multiply to each denominator to get that number and multiply the numerator by the same amount

(3/4 * 5/5) + (6/10 * 2/2)=

15/20 + 12/20

Then add

15/20 + 12/20= 27/20

Then finally convert to mixed number

27/20 = 1 7/20
