Answer:13/10 = 1 3/10.Step-by-step explanation:Think of tenths like slices out of 10.You have 9/10 (9 slices out of 10).You add 4/10 (4 more slices out of 10).Since the pieces are the same size (tenths), add the top numbers: 9 + 4 = 13.So you get 13/10. That’s an improper fraction.Turn it into a mixed number: 13/10 = 1 whole and 3/10.Answer: 13/10 = 1 3/10.
