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.
