Introduction to Subtract a Fraction from a Whole Number

Subtracting a fraction from a whole number involves decomposing the whole number into an equivalent mixed number, which can then be subtracted from the given fraction. This process enables us to grasp the concept of removing a part from a whole and express the result in its simplest form. Mastering this operation empowers us to solve real-world problems, ranging from recipe adjustments to distance calculations.

Step-by-Step Guide to Subtract a Fraction from a Whole Number

Now, let’s delve into the step-by-step process of subtracting a fraction from a whole number, breaking it down into manageable and easy-to-follow steps:

Step 1: Decompose the Whole Number into a Mixed Number

Convert the whole number into a mixed number by dividing it by the denominator of the fraction. The quotient becomes the whole number in the mixed number, and the remainder becomes the numerator of the fraction.

Step 2: Subtract the Numerators

Subtract the numerator of the fraction being subtracted from the numerator of the mixed number. The resulting number is the numerator of the difference.

Step 3: Preserve the Denominators

The denominator of the fraction remains the same throughout the subtraction process and becomes the denominator of the difference.

Step 4: Simplify the Mixed Number, if Necessary

If the numerator of the difference is greater than or equal to its denominator, convert the mixed number back into a whole number by dividing the numerator by the denominator.

Examples and Real-World Applications

To solidify your understanding of subtracting a fraction from a whole number, let’s explore some practical examples:

Example 1: Baking Bonanza

Suppose you’re following a delectable baking recipe that calls for 1 1/2 cups of flour. However, you only have 1 cup of flour readily available. How much flour do you need to borrow from your neighbor?

Solution: Convert 1 cup to the mixed number 1 0/2. Subtract 0/2 from 1 1/2: 1 1/2 – 0/2 = 1 1/2. Therefore, you need to borrow 1 1/2 cups of flour from your neighbor to complete your baking adventure.

Example 2: Marathon Measurement

A marathon runner has completed 21 kilometers of the 42-kilometer race. How many more kilometers does this determined athlete have left to conquer?

Solution: Convert 21 kilometers to the mixed number 21 0/1. Subtract 0/1 from 42: 42 – 0/1 = 42. The runner has 21 kilometers left to complete the marathon.
