# How Do You Change Proper Fractions Into Improper Fractions?

You have to make the sum hav the numerator larger that the denominator
thanked the writer.
A proper fraction is a fraction whose numerator is less than the denominator. An improper fraction is one whose numerator is more than the denominator. To convert a proper fraction to an improper fraction, you need to increase the magnitude of its value--make it be something it isn't.

To convert a mixed number to an improper fraction, you add the fraction numerator to the integer times the denominator.
a + b/c = (ac + b)/c

1 2/3 = (1*3 + 2)/3 = 5/3

The answer has an example. Consider the mixed number 1 2/3. This is the integer 1 added to the fraction 2/3. The numerator of the fraction is 2. The denominator of the fraction is 3.
To convert to an improper fraction, multiply the integer (1) times the denominator (3) and add the numerator (2). 1*3+2 = 3+2 = 5. Now, express this result over the denominator. 5/3
1 2/3 = 5/3
Another example: 2 3/5 = (2*5 + 3)/5 = 13/5
