To convert 80 percent into a fraction, we start by understanding what 'percent' means. The term "percent" refers to a ratio per hundred. Therefore, 80 percent can be written as:
80% = 80/100
Now, we can simplify this fraction. To do that, we need to find the greatest common divisor (GCD) of the numbers in the fraction, which in this case are 80 and 100. The GCD of 80 and 100 is 20.
Next, we divide both the numerator (80) and the denominator (100) by their GCD (20):
- Numerator: 80 ÷ 20 = 4
- Denominator: 100 ÷ 20 = 5
Thus, we can simplify the fraction:
80/100 = 4/5
Therefore, 80 percent can be expressed as the fraction 4/5.
In summary:
- 80 percent = 80/100
- Simplified, it becomes 4/5
This fraction, 4/5, indicates that when something is 80% of a whole, it represents four parts out of five total parts in that whole. This is useful to know in various practical applications, such as cooking, budgeting, and many areas of academics.
