$5 \cdotp 565 \, 01$ 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 $5 \cdotp 56$.

$5 \cdotp 565 \, 01$ 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 $5 \cdotp 56$.

$5 \cdotp 565 \, 01$ 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 Place

$12 \cdotp 5664$ 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 $12 \cdotp 56$.

$12 \cdotp 5664$ to Two Significant Figures
