$0 \cdotp 0435$ to Nearest Thousandth
$0 \cdotp 0435$ rounded to the nearest thousandth is $0 \cdotp 044$.
We have that $0 \cdotp 0435$ is half way between $0 \cdotp 043$ and $0 \cdotp 044$, and the convention is to round to the nearest even digit.
$4 \cdotp 500 \, 01$ to Nearest Unit
$4 \cdotp 500 \, 01$ rounded to the nearest unit is $5$.
This is because $4 \cdotp 500 \, 01$ is closer to $5$ than $4$.
$143 \cdotp 95$ to Nearest Tenth
$143 \cdotp 95$ rounded to the nearest tenth is $144 \cdotp 0$.
We have that $143 \cdotp 95$ is half way between $143 \cdotp 9$ and $144 \cdotp 0$, and the convention is to round to the nearest even digit, which in this case is $0$.
$368$ to Nearest Hundred
$368$ rounded to the nearest hundred is $400$.
This is because $368$ is closer to $400$ than $300$.
$24 \, 448$ to Nearest Thousand

This is because $24 \, 448$ is closer to $24 \, 000$ than $25 \, 000$.
$5 \cdotp 565 \, 00$ to Nearest Hundredth
$5 \cdotp 565 \, 00$ rounded to the nearest hundredth is $5 \cdotp 56$.
We have that $5 \cdotp 565 \, 00$ is half way between $5 \cdotp 56$ and $5 \cdotp 57$, and the convention is to round to the nearest even digit.
$5 \cdotp 565 \, 01$ to Nearest Hundredth
$5 \cdotp 565 \, 01$ rounded to the nearest hundredth is $5 \cdotp 57$.
This is because $5 \cdotp 565 \, 01$ is closer to $5 \cdotp 57$ than $5 \cdotp 56$.
$12 \cdotp 5664$ to One Decimal Place
$12 \cdotp 5664$ rounded to $1$ decimal place is $12 \cdotp 6$.
This is because $12 \cdotp 5664$ is closer to $12 \cdotp 6$ than it is to $12 \cdotp 5$.
$12 \cdotp 5664$ to Two Decimal Places
$12 \cdotp 5664$ rounded to $2$ decimal places is $12 \cdotp 57$.
This is because $12 \cdotp 5664$ is closer to $12 \cdotp 57$ than it is to $12 \cdotp 56$.
$1 \cdotp 576$ and $1 \cdotp 5751$ to Two Decimal Places
$1 \cdotp 576$ and $1 \cdotp 5751$ rounded to $2$ decimal places are both $1 \cdotp 58$.
This is because they are both closer to $1 \cdotp 58$ than they are to $1 \cdotp 57$.
$1 \cdotp 572$ and $1 \cdotp 5749$ to Two Decimal Places
$1 \cdotp 572$ and $1 \cdotp 5749$ rounded to $2$ decimal places are both $1 \cdotp 57$.
This is because they are both closer to $1 \cdotp 57$ than they are to $1 \cdotp 58$.
$12 \cdotp 5664$ to Two Significant Figures
$12 \cdotp 5664$ rounded to $2$ significant figures is $13$.
This is because $12 \cdotp 5664$ is closer to $13$ than it is to $12$.
$419 \cdotp 8$ to Three Significant Figures
$419 \cdotp 8$ rounded to $3$ significant figures is $420$.
This is because $419 \cdotp 8$ is closer to $420$ than it is to $419$.
$0 \cdotp 02006$ to Three Significant Figures
$0 \cdotp 02006$ rounded to $3$ significant figures is $0 \cdotp 0201$.
This is because $0 \cdotp 02006$ is closer to $0 \cdotp 0201$ than it is to $0 \cdotp 0200$.
Also note that the $0$ immediately to the right of the decimal point does not count as one of the significant figures.
