Understanding Decimals and Whole Numbers
Before we dive into multiplying whole numbers by decimals, let's quickly review what decimals and whole numbers are. Decimals are numbers that have a fractional part separated by a decimal point. For example, 0.5, 3.14, and 2.75 are all decimals. Whole numbers, on the other hand, are numbers without a fractional part. Examples of whole numbers include 1, 2, 3, and 100.
Why is Multiplying Whole Numbers by Decimals Important?
Multiplying whole numbers by decimals is a crucial math operation that has numerous real-world applications. For instance, when shopping, you might need to calculate the total cost of an item that's on sale for 25% off its original price. To do this, you'll need to multiply the original price by the decimal equivalent of 25% (0.25). Similarly, in science and engineering, decimals are used to represent precise measurements, and multiplying whole numbers by decimals is essential for solving problems involving these measurements.
Multiplying Whole Numbers by Decimals: Step-by-Step Guide
Now that we've covered the basics, let's move on to the step-by-step guide on how to multiply whole numbers by decimals.
- Write the problem: Write the multiplication problem with the whole number and decimal.
- Multiply the numbers: Multiply the whole number by the decimal as if it were a whole number. Ignore the decimal point for now.
- Count the decimal places: Count the number of decimal places in the decimal number.
- Place the decimal point: Place the decimal point in the product (the result of the multiplication) based on the number of decimal places you counted in step 3.
- Check your answer: Check your answer to make sure it makes sense.
