Question

Explain how you would round the numbers 33 and 89 to estimate their sum.

Answer 1

Answer:

The normal rule of rounding off is if the last number is below 5 it is rounded off to the same number and if it is above five it is rounded off to the number immediately after it.

So 33 is can be rounded off to 30 and the number 89 can be rounded off to 90.  

Summing up we will get 30 + 90 = 120.
