QUESTION A
The given decimal is
[tex]5.39562[/tex]
We want to round the given decimal to the nearest thousandth.
This means that, we are rounding to three decimal places.
In
[tex]5.39562[/tex]
the number in the third decimal place or the thousandth digit is 5.
The next number after the thousandth digit is 6, so we need to round up to get,
[tex]5.39562 \approx5.396[/tex]
to the nearest thousandth.
QUESTION B
The given decimal is
[tex]0.12345[/tex]
We want to round the given decimal to the nearest thousandth or to three decimal places.
We start counting from the first number after the decimal point.
The number in the third decimal place or the thousandth digit is 3.
The next number after 3 is 4, which is less than 5 so we round off.
This means we will not add 1 to the number in the thousandth digit.
This implies that,
[tex]0.12345 \approx0.123[/tex]
to the neatest thousandth.
QUESTION C
The given decimal is
[tex]0.5634[/tex]
The number in the third decimal place or the thousandth digit is 3.
The number after 3 is also less than 5 so we will not add 1 to the thousandth digit.
This means that,
[tex]0.5634 \approx0.563[/tex]
to the nearest thousandth.
QUESTION D
The given decimal is
[tex]18.93763[/tex]
We want to round to the nearest thousandth.
The thousandth digit is 7, the number after 7 is 6 which is greater than or equal to 5 so we round up to obtain,
[tex]18.93763 \approx18.938[/tex]
to the nearest thousandth.
