Question

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

Answer 1

30 and 90 is equal to 120

Answer 2

Solution :-

Here is the general rule for rounding off any number -

# If the number you are rounding is followed by 5, 6, 7, 8 or 9, round off the number up.

Example : 77 rounded to the nearest ten is 80

# If the number you are rounding is followed by 0, 1, 2, 3 or 4, round the number down.

Example : 53 rounded to the nearest ten is 50

33 ⇒ 30

89 ⇒ 90

Sum - 30 + 90

= 120
