Question

1. Estimate the following to the nearest hundreds :
(a) 475990 – 15387
(b) 574 + 898
(c) 35525 + 65417
(d) 825 X 852
(e) 475 - 71​

Answer 1

Answer:

(a) 460600

(b) 1500

(c) 100900

(d) 702900

(e) 400

Step-by-step explanation:

(a) 475990 – 15387 = 460603

last two digits are 03 which is less than the mid value 50 hence it is rounded to 460600

(b) 574 + 898 = 1472

last two digits are 72 which is greater than the mid value 50 hence it is rounded to 1500

(c) 35525 + 65417 = 100942

last two digits are 42 which is less than the mid value 50 hence it is rounded to 100900

(d) 825 X 852 = 702900

last two digits are 00 hence no rounding off

(e) 475 - 71​ = 404

last two digits are 04 which is less than the mid value 50 hence it is rounded to 400
