How Form 8865 Percentage 2024

G'day, welcome to the Tech Math Channel. In this video, we will be looking at a fast and easy way to calculate percentages in your head, without the need for a calculator. Let's start with an example: 30% of 40. The answer is 12. Let me explain how I arrived at this answer quickly. To begin, let's set up the equation: 30% is equal to 30 out of 100, and 40 is equivalent to 40 out of 1. We can cancel out the zeros, which means dividing both parts by 10. 30 divided by 10 is 3, and 40 divided by 10 is 4. Therefore, 3 times 4 equals 12. Now, let's try another example: 20% of 18. We can cancel out the zeros again, leading to 2 times 18, which equals 36. Another example: 50% of 40. Since there are two zeros to cancel out, we have 5 times 4, which equals 20. What if the number is not a multiple of ten? Let's revisit the previous example of 20% of 18. We divide 18 by 10, resulting in 1.8. Then, we multiply 2 times 1.8, which equals 3.6. Let's do one more example: 30% of 12. We divide 12 by 10, which gives us 1.2. Then, we multiply 3 times 1.2, resulting in 3.6. These calculations are quite straightforward, but as the numbers get larger, it can become more challenging. For instance, calculating 65% of 82 requires a different approach. If you're interested, I have a video that explains how to tackle these more complex calculations. Even if you can't them mentally yet, you can still use a calculator to get the correct answer. I will provide a link to the video for your reference. In conclusion, this method is an easy and efficient way to calculate percentages mentally....
