How do you write a decimal in expanded form as a fraction?
It is quite simple to change a decimal form into a fraction. Any number , including a decimal can be divided by 1, and multiplied by 1. Take the decimal .156 for example first divide it by 1; yields .156/1 now do some fraction multiplication (.156/1) x (1000/1000) (note 1000/1000 =1, so mult of the decimal dosen't change its value) this yields 156/1000 , so .156 = 156 thousandths ------------------------------------------------------------------ A more interesting problem arises from trying to expand a repeating decimal example .175175175175175............and so on Let X =.175175175175175.......... then 1000X=175.175175175......... (note the decimal place after 175) so 1000X-1X=999X = 175 then dividing by 999 gives x=175/999 so .175175175.........=175/999 as a fraction.
