Question

Estimate 275 + 238 to nearest hundred.

  1. 400
  2. 500
  3. 600
  4. 700

hintHint:

Estimate 275 and 238 to the nearest hundreds individually and then add.

The correct answer is: 500

Estimate 275 + 238:
275  → 300   (Since 275 is closer to 300, the estimate for the nearest hundreds will be 300)
238  → 200  (Since 238 is closer to 200, the estimate to nearest hundreds will be 200)
Now, calculate:
275 + 238
After estimating:
300 + 200 = 500
The correct option is (b) 500
