This guide provides a step-by-step approach to solving "70% of 64," empowering you to tackle similar percentage problems with confidence. What is often perceived as a difficult concept becomes easily approachable once you understand the basic underlying principles.
Did you know that understanding percentages can help you make informed decisions about savings, investments, and even grocery shopping? This simple calculation opens doors to a deeper understanding of quantitative analysis.
Deconstructing the Problem: 70% of 64
The phrase "70% of 64" asks: what is 70/100ths of the number 64? This translates to finding a specific portion (70%) of a larger quantity (64). Think of it as finding 70 out of every 100 equal parts of 64.
Calculating 70% of 64: A Step-by-Step Guide
Here's a clear and concise method to solve this problem. We'll break it down into easily digestible steps, clarifying both the what and why of each action.
Step 1: Convert the Percentage to a Decimal
To make the calculation easier, convert 70% to its decimal equivalent. Divide the percentage by 100:
70 / 100 = 0.7
Why? Percentages are essentially fractions with a denominator of 100. Changing to a decimal gives us a more manageable format for multiplication.
Step 2: Multiply the Decimal by the Whole Number
Now, multiply the decimal (0.7) by the whole number (64):
0.7 * 64 = 44.8
This step directly calculates the portion representing 70% of 64.
Step 3: The Solution
The result, 44.8, is the answer. Therefore, 70% of 64 is 44.8. This simple calculation shows how easily you can solve seemingly complex percentage problems.
