Question

In the sums given below, round off the numbers
to the nearest hundred and find the estimated
answer. Also, find the actual answer.
(1 2213 +6792 (ii) 8346 + 9042
(iii) 2849 + 3126 (iv) 4545 + 5863
(v) 7923 + 3021​

Answer 1

Answer:

i) 2213+6792=9005  estimate=9000

ii) 8346+9042=17388   estimation=17000

iii) 2849+3126=5975   estimation=6000

iv) 4545+5863=10408   estimation=10000

v)7923+3021=10944   estimation=11000

Step-by-step explanation:

First question Estimation

i) 2213+6792

The number after the 2 in 2213 is smaller than 5 which means we are going to round down so it will give you 2000

The number after the 6 in 6792 is bigger than 5 which means we are rounding up so it will be 7000 not 6000

Then we add both of the numbers (2000 +7000) together to get an answer of 9000 as an estimation.
