Answer 2

10 sets of 9 + 10 = 10 tens

Step-by-step explanation:

• Let us understand that "sets' means "number of times" a number exists.

• Here "10 sets of 9" means, 9 exists 10 times. So its value is (10 * 9) = 90

• Now, 10 sets of 9 + 10 = 90 + 10 = 100

• We have to find it in terms of "tens". Let us divide 100 by 10 and see how many times 10 exists in 100.

• 100 ÷ 10 = 10

Answer: 10 sets of 9 + 10 = 10 tens
