So you know that there are 51 states in the US. 49/51 are apart of the continental US.
To find that percentage, all we need to do is divide 49 by 51 and convert the decimal we get into a percentage.
49/51= 0.9607...
To convert this into a percentage, we multiply it by 100. This is the equivalent of moving the decimal point over two places to the right.
49/51= 96.07% of the states are part of the continental US
Does this make sense? Hope it helped!
