To determine

To round the decimal number $28.17$ to ones.

Answer to Problem 44CCR

  $28$

Explanation of Solution

Given information:

The decimal number: $28.17$ .

Concept Used:

• To round to the ones of a decimal number, round the first digit before decimal.

  

• If the number right to the digit, we’re rounding off, is greater than 5 then add 1 to the rounding digit but if the number to the right of the digit is less than 5 then drop it.

Calculation:

In order to round the decimal number $28.17$ to nearest once, round off the first digit before the decimal point. Observe that the digit after decimal is 1, which is less than 5, so drop the digits to the right of decimal point. So, after rounding off to nearest ones, the given decimal becomes

  $28.17=28$

Thus, the decimal number rounded to nearest ones is $28$ .
