An easier way of finding the percentage of a decimal is:
Pin-point the decimal point. Move it two place values over. Make it a percentage.
0.142 => 14.2%
Of course, you can still change it to a fraction (over 100), and then change it to a percentage.
0.142 => 142/1000 = 14.2/100 = 14.2%
14.2% is your answer
hope this helps
