299 + 399 = 698.

Explanation:
In the above-given question,
given that,
299 + 399.
so for this problem, Tracy used four different solutions.
place value chart is easy for Tracy.
2 hundred = 200.
9 tens = 90.
9 ones = 9.
200 + 90 + 9 = 299.
3 hundred = 300.
9 tens = 90.
9 ones = 9.
300 + 90 + 9 = 399.
299 + 399 = 698.

Question 2.
Choose the best strategy and solve. Explain why you chose that strategy. 221 + 498 = 719.
467 + 200 = 667.
378 + 464 = 842.

Explanation:
In the above-given question,
given that,
2 hundred = 200.
