Question

Choose the decimal (s) from the brackets which is (are) not equivalent to the given decimals:
$45.05(45.050,45.005,45.500,45.0500)$

Answer 1

There is no value of $0$ after added to right hand side of last digit of decimal.

So, $45.05=45.050=45.0500=\mathrm{45.05000...}$

But $0$ is added in between two digits or any digits are shuffled fromoriginal number then the value of number changes

$\therefore 45.05\ne 45.005$ and $45.05\ne 45.500$

So, $45.005,45.500$ are not equivalent to $45.05$
