What is bigger 0.7 or 0.16?

To compoare any pair of decimals

First bring both decimals to the same number of decimal places by inserting suffix 'zeroes' .

Hence

0.7 - 0.70

0.16 - 0.16 # Both are now to 2 decimals places.

0.70 & 0.16

Drop the decimal point

070 & 016

Drop the prefic 'zero'.

70 & 16

It should be obvious theta 70 > 16.

Hence it follows that 0.7 > 0.16

This method is good for comparison of any pair of decimal numbers.
