Question

Istimated difference of 43209 and 3479 round off nearest hundred

Answer 1

Answer :

Estimation : Estimation refers to rounding off a numeral to its nearest 10, 100, 1000,..., and so on. It conveys the approximate value.

Now,

When 43209 is estimated to its nearest hundred, its hundred place '2'  would be round off according to the nearest place. In this numeral it is given that its hundred '209' is very near to 200 as compared to 300. So we will estimate it to 43200.

When 3479 is estimated to its nearest hundred, its hundred place '4' would be round off according to the nearest place. In this numeral it is given that its hundred '479' is very near to 500 as compared to 400. So we will estimate it to 3500.

Difference between the two : When we would estimate the difference of 43209 and 3479, we would use the estimated values 43200 and 3500.

So the difference would be

$43200 - 3500\\=39700$
