What is an 'Improper Fraction?'

An improper fraction is a fraction where the numerator is larger or greater than the denominator.

An example would be:

How to change an Improper
improperfractions1

Step 1: Mark the numerator.

improperfractions2

Step 2: 'Flip' the mark over. Now your dividend and divisor are in place.

 

 

Now you divide. We are using short-cut division here and doing the subtraction and re-grouping in our heads. The remainder is placed up along the top of the number (it looks like an exponent but it is NOT an exponent).

improperfractions2a

remainder of 1 is the numerator

Step 3: Take the remainder. In this case, the remainder was 1. This now becomes the numerator. The denominator remains the same (4).

original denominator remains the same (4)

Step 4: Put the fraction next to the whole number. You now have your answer! You have converted an improper fraction into a mixed number.

How to change an Improper

Let's say you have already done all the work above and you want to convert that fractional amount into a decimal. WELL, you've already done all the 'hard' work…you just need to change that remainder into a decimal! Yep, that's it! The fractional remainder is what becomes the decimal amount.

Let's get to it, shall we?

Step 1: Leave the whole number (2) alone. You only need to work with the fraction. Just like when converting an improper fraction to a mixed number, you need to mark the numerator.

Step 2: Flip the mark over.

Step 3: Place a decimal point above the division bar. Include a decimal AND several zeroes for place-holders AFTER the dividend (in this case, the 1). The zeroes do not add any value; they are simply place-holders.

improperfractions2h

Step 4: Divide, just like you normally would. The example shows the short-cut division where the remainders are placed within the dividend. When you have NO remainder, then you are finished!

Step 5: Tack the decimal onto the whole number.
