Question

Which of the following numbers is equal to the rounded value of seventeen and thirty-four thousandths to its nearest tenth?

• A. 17.4
• B. 17.2
• C. 17
• D. 17.3

Answer 1

The correct option is C 17

Express the number name as a decimal.
Whole part: Seventeen = 17
Fractional part: Thirty-four thousandths = 0.034
Decimal = 17.034
Digit at the tenths place = 0
Digit at the hundredths place = 3
3 < 5
Hence, the decimal must be rounded down by keeping the digit at the tenths place the same and replacing all digits at smaller places with zero.
Replace all the digits to the right of the tenths place with zero.
Rounded decimal = 17.0 = 17
So, 17.034 rounded to the nearest tenth is 17.
