Three Types of Fractions

There are three types of fraction:

1⅞ ⅞ ⅞ 1

proper fraction improper fraction mixed fraction

Mixed Fractions or Improper Fractions

You can use either an improper fraction or a mixed fraction to show the same amount.

1⅞ = 15

8

Mixed Fractions or Improper Fractions

You can use either an improper fraction or a mixed fraction to show the same amount.

1⅞ = 15

8 1 whole = 8 parts

Multiply the whole number by the denominator:

1 × 8 = 8

Add the numerator to that:

8 + 7 = 15

Then write that down above the denominator,

like this:

1⅞ = 15

Convert to an improper fraction

Converting Mixed Fractions to Improper Fractions

1. Multiply the whole number part by the fraction's denominator.

2. Add that to the numerator 3. Write that result on top of the denominator.

To convert a mixed fraction to an improper fraction, follow these steps:

Let’s try another example

together!

Divide the whole number by the denominator:

15 ÷ 8 = 1 with remainder of 7

Place the remainder above the denominator

like this:

1⅞ = 15

8

Convert to a mixed fraction

1. Divide the numerator by the denominator. 2. Write down the whole number answer 3. Then write down any remainder above the

denominator.
