Question
If Zoe must round off 73.6179 up to 2 digits. What is the correct answer?
- 73.62
- 73.61
- 73.70
- 73.60
Hint:
Rounding off means a number is made simpler by keeping its value intact but closer to the next number
The correct answer is: 73.62
Step 1 of 1:
We have given Zoe must round off 73.6179 up to 2 digits.
If the critical digit is 0, 1, 2, 3 or 4, then round down.
If the critical digit is 5, 6, 7, 8 or 9, then round up.
So, 73.6179 rounded off to 2 digits is 73.62, because 7 (third digit) is greater than 5, so, we need to round up.
If the critical digit is 0, 1, 2, 3 or 4, then round down.
If the critical digit is 5, 6, 7, 8 or 9, then round up.
