What is the value of  
7
8
  rounded off to second decimal place?


Answer:

0.88

Step by Step Explanation:
  1. Let us convert  
    7
    8
      into decimal form.

     

    7
    8
      = 0.875

  2. Remember: To round off a number to the second decimal place, we look at the third decimal place.

    If the digit at third decimal place is less than 5, the digits after the second decimal place disappear.

    In case the digit at the third decimal place is 5 or greater than 5, we increase the digit at the second decimal place by 1 and the all the digits to the right of the second decimal place disappear.

  3. We find that the digit at the third decimal place of 0.875 is 5. So, the digit at the second decimal place becomes 7 + 1 = 8 and all the digits to the right of the second decimal place disappear.
  4. Thus, 0.875 can be rounded off to the second decimal place as 0.88.
