Just divide it out! Let's take the improper fraction 7/2 which can be asked as the question "How many times does two go into seven?" Seven divided by two on will give you a little more than three, 3 and a half (1/2) to be exact.
Decimals are all units of ten. So to convert the remainder into decimal, change it into an equivalent fraction with the denominator of 10.
1/2 = 5/10 (because ten divided by two is five)
Take that numerator and place it behind the decimal point.
7/2 = 3.5
There you go, you just survived fractions!
