Find the pairs that are equal. Share your thinking in class.

Correct Answer

Step 1: Calculate 516 + 100 = 616

Step 2: Calculate 615 - 200 = 415

Step 3: Calculate 350 + 50 = 400

Step 4: Calculate 400 + 15 = 415

Step 5: Calculate 450 - 50 = 400

Step 6: Calculate 816 - 200 = 616

Step 7: Match equal values: 415 pairs, 400 pairs, 616 pairs

Answer: Equal pairs are: (615 – 200 = 415) equals (400 + 15 = 415) (350 + 50 = 400) equals (450 – 50 = 400) (516 + 100 = 616) equals (816 – 200 = 616)
