Question

Estimate each difference to the nearest hundred :

(i) 769 – 314

(ii) 856 – 687

(iii) 6352 – 2086

Answer 1

(i) 769 – 314

769 to the nearest hundred = 800 and, 314 to the nearest hundred = 300

∴ Required difference = (800 – 300) = 500

(ii) 856 – 687

856 to the nearest hundred = 900 and, 687 to the nearest hundred = 700

∴ Required difference = (900 – 700) = 200

(iii) 6352 – 2086

6352 to the nearest hundred = 6400 and, 2086 to the nearest hundred = 2100

∴ Required difference = (6400 – 2100) = 4300
