Use the calculator below to find the answer to a fraction minus a whole number problem.

It is possible to subtract a whole number from a fraction and vice versa. In this article I will show you how to subtract a whole number from a fraction the parts of a fraction and the types of fraction.

## Parts of a fraction

Let’s use A/B for illustration purpose.

**A **is the numerator

**B** is the Denominator

**/ **is the separator that separates the numerator and the denominator

## How to subtract a whole number from fractions

There are two methods to subtract a whole number from a fraction. The first method is by finding LCM while the second one is by cross multiplication

### Method 1: By finding LCM

**Step 1:** Rewrite the whole number as a fraction

**Step 2:** Find the LCM of the two fractions (Here is an LCM guide)

**Step 3:** Use the LCM to convert the whole number to have the same denominator as the fraction (Multiply the whole number with a fancy form of 1)

**Step 4:** Now you can subtract them directly since they have equal denominators

**Example 1: What is 5/2 – 9?**

**Step 1:** 5/2 -9/1

**Step 2:** The LCM of 2 and 1 is 2

**Step 3:** 9/1 × 2/2 =18/2

Therefore the new problem is 5/2 – 18/2

**Step 4:** 5/2 – 18/2 =-13/2

**Thus 5/2 minus 9 is equal to -13/2**

**Example 2: What is 10/3 minus 3**

**Step 1:** 10/3 – 3/1

**Step 2:** The LCM of 3 and 1 is 3

**Step 3:** 3/1 × 3/3 = 9/3

Therefore the new problem is 10/3 -9/3

**Step 4:** 10/3 – 9/3 = 1/3

**Thus 10/3 minus 3/1 is equal to 1/3**

## Method 2: By cross-multiplication

**Step 1:** Convert the whole number to a fraction by dividing it by 1

**Step 2:** Write your new problem

**Step 3:** Multiply the first numerator by the second denominator

**Step 4:** Multiply the first denominator by the second numerator

**Step 5:** Multiply both denominators

**Step 6:** Subtract the numerators

**Step 7:** Write the answer in its simplest form

*Example : What is 4/3 – 6?*

*Example : What is 4/3 – 6?*

**Step 1:** 6/1

**Step 2:** 4/3 – 6/1

**Step 3:** 4 × 1

**Step 4:** 3 x 6

**Step 5:** (4 × 1) – (3/6) / (3 × 1)

**Step 6:** -4 2/3

**Thus 4/3 minus 6 is equal to -4 2/3**

## Types of Fraction

**Proper fraction**

A proper fraction is the normal fraction in which the numerator is less or equal to the denominator. Examples of proper fractions include: **½, 1/3, ¼, 1/5, 1/6,**

**Improper fraction**

Improper fraction refers to a fraction with a larger numerator than the denominator: Examples of improper fractions include: **2/1, 5/2, 4/3, 9/4/, 20/6**

**Mixed fraction**

A mixed fraction refers to a combination of whole numbers and fractions. Examples of Proper fractions include: **2 1/3, 4 1/5, 6 4/9, 10 5/6**

**Like Fractions**

Like fractions refer to fractions that share the same denominator. Examples of like fractions include: **2/3, 5/3, 6/3, 7/3, 8/3**

**Unlike Fractions**

Unlike fractions are the opposite of like fractions. These are fractions that share different denominators, Examples of unlike fractions include: **½, 10/23, 30/50, 4/5, 7/9**

**Equivalent fractions**

Equivalent fractions refer to two fractions that represent the same portion of a whole. In short terms they are equal when simplified. Examples of equivalent fractions include: **2/4 and ½, 3/9 and 1**
