a) \[13.0\]
b) \[13.7\]
c) \[13.8\]
d) \[14.0\]

Answer 1

Hint: Rules for rounding decimals to the nearest tenths:
1. To round a decimal analyse the digit at the hundredths place.
2. If the hundredths place value is 5 or more than 5, then the digit at the tenths place increases by 1 and the digits at the hundredths place and thereafter becomes zero.
3. If the hundredth place value is less than 5, then the digit at the tenths place remains unchanged and the digits at the hundredths place and thereafter become zero.

Complete step-by-step answer:
We use the following rules to round \[13.7\] to the nearest tenth:
A) If the last digit in the fractional part of \[13.73\] is less than 5, then simply remove the last digit of the fractional part.
B) If the last digit in the fractional part of \[13.73\] is 5 or more and the first digit in the fractional part is less than 9, then add 1 to the first digit of the fractional part and remove the second digit.
C) If the last digit in the fractional part of \[13.73\] is 5 or more and the first digit in the fractional part is 9 then add 1 to the Integer part and make the fractional part 0.
With \[13.73\], rule A applies and the answer is \[13.7\]
