Add 2/5 and 7/10.

Explanation:
When adding fractions, you must combine parts that share the same size of piece, so you need a common denominator. For 2/5 and 7/10, the common denominator is 10. Convert 2/5 to 4/10, then add 4/10 + 7/10 = 11/10. This can also be written as 1 1/10. So the sum is 11/10 (which is greater than 1). The other options represent 9/10 (less than a whole), 1 (exactly a whole), and 13/10 (one and three tenths), which don’t match the actual sum.
