Question

Give a rough estimate $($ by rounding off to nearest hundred $)$ and also a closer estimate $($ by rounding off to nearest tens $)$ of each of the following$:$

$106630-53599$

Answer 1

The given numerical expression is $106630-53599$

First find the given summation nearest to ten's

Nearest tens to $106630$ is $=106630$

Nearest tens to $53599$ is $=53600$

Required difference $=106630-53600$

$=53,030$

Now find the given summation nearest to hundredths

Nearest hundred to $106630$ is $=106600$

Nearest hundred to $53599$ is $=53600$

Required difference$=106600-53600$

$=53000$

Hence$,$ the given difference nearest to ten's and hundred are $53,030$ and $53000$ respectively$.$
