Question

approximate the nearest number and multiply a. 79×43 b. 49 ×347 c. 292 ×312 d. 32 ×2598​

Answer 1

Answer:

In case of two digit numbers we can only round the number to the nearest tens place i.e. only one place estimate.

For example, let us estimate the following sums:

(i) 47 + 32

We need to round the number to the nearest 10.

47 → 50

32 → 30

50 + 30 = 80
