Question

If Zoe must round off 73.6179 up to 2 digits. What is the correct answer?

  1. 73.62    
  2. 73.61    
  3. 73.70    
  4. 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.
