Answer to Problem 47CCR

  $6.1$

Explanation of Solution

Given information:

The decimal number: $6.05$ .

Concept Used:

• To round to the nearest tenth of a decimal number, round the first digit after decimal.

  

• If the number right to the digit, we’re rounding off, is greater than or equal to 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 $6.05$ to nearest tenths, round off the first digit after the decimal point. Observe that the second digit after decimal is5, which is equal to 5, so add 1 to the first digit after decimal. So, after rounding off to nearest tenths, the given decimal becomes

  $6.05=6.1$

Thus, the decimal number rounded to nearest tenths is $6.1$ .
