A. Add 100 + 90 + 2
B. Evaluate (563 - 200) + 8
C. Subtract 571 - 200

Answer 1

B and C

Explanation:

A = 192

B = (563 - 200) + 8 = 371

C = 571 - 200 = 371

Answer 2

Answer:

C. Subtract 571 - 200

Explanation:

563 - 192

We can make 192 to 200 by adding 8

So if I add 8 to 192 I have to add 8 to 563

563 + 8 = 571

192 + 8 = 200

571 - 200 = 563 - 192

371 = 371

Therefore our answer is C.
