Today, we’re tackling a common one: 4/5. What exactly is 4/5 as a percent? Don’t worry; we’ll break it down step-by-step so that you’ll understand not just the answer, but also why it’s the answer. Get ready to boost your math confidence!
Unlocking the Mystery
Percentages are just a way of expressing a fraction with a denominator of 100. Think of it like slicing a pie into 100 pieces. A percentage tells you how many of those 100 pieces you have. So, to turn 4/5 into a percentage, we want to figure out what fraction is equivalent to 4/5 but has 100 as its bottom number.
To do this, we need to find a number that we can multiply the denominator (5) by to get 100. In this case, 5 multiplied by 20 equals 100. Now, and this is important, whatever we do to the bottom of the fraction, we must do to the top! So, we also multiply the numerator (4) by 20.
That gives us (4 20) / (5 20), which simplifies to 80/100. See that? We’ve successfully turned our fraction into one with a denominator of 100. And that makes finding the percentage super simple: 80/100 is the same as 80 percent! So, 4/5 as a percent is 80%.
Another way to think about it is to first convert 4/5 to a decimal. To do this, simply divide 4 by 5, which gives you 0.8. Then, to convert the decimal to a percentage, multiply by 100. So, 0.8 * 100 = 80%. Again, we arrive at the answer: 80%.
You can use this method for converting any fraction into a percentage. Just remember the key steps: find an equivalent fraction with 100 as the denominator or convert the fraction to a decimal and then multiply by 100. Practice makes perfect, so try it with other fractions too!
Now that you know 4/5 is 80%, you can use this knowledge in real-world scenarios, from calculating a tip on a restaurant bill to understanding sales discounts. Embrace the power of percentages; they truly make numbers more relatable and easier to understand. Keep practicing, and you’ll be a percentage pro in no time!
