Which is the biggest 0.766 or 0.77?

0.766 & 0.77

To compare decimals , brinf both decimals to the same number of decial places by inserting suffix zeroes.

Hence

0.766 & 0.770

Drop the prefix zero ans the decimal point

Hence

766 & 770

I think it should be obvious that 770 > 766 by '4; places.

Hence it follows that 0.77 > 0.766
