Simplifying the Fraction: Finding the Lowest Terms
The first step in understanding 80/280 is simplifying it to its lowest terms. This means finding the greatest common divisor (GCD) of both the numerator (80) and the denominator (280) and dividing both by that number. Let's find the GCD.
We can use several methods to find the GCD. One common method is prime factorization. Let's break down 80 and 280 into their prime factors:
- 80: 2 x 2 x 2 x 2 x 5 = 2⁴ x 5
- 280: 2 x 2 x 2 x 5 x 7 = 2³ x 5 x 7
The common prime factors are 2³ and 5. Multiplying these together gives us 2³ x 5 = 40. Because of this, the GCD of 80 and 280 is 40 Not complicated — just consistent..
Now, we divide both the numerator and the denominator by 40:
80 ÷ 40 = 2 280 ÷ 40 = 7
Because of this, the simplified fraction is 2/7. Practically speaking, this simplified form makes it much easier to understand and work with the fraction. Using the simplified fraction also prevents any potential rounding errors when performing calculations Which is the point..
Converting to Percentage: Expressing the Fraction as a Proportion
Converting the fraction 80/280 (or its simplified form, 2/7) to a percentage allows us to express it as a proportion out of 100. To do this, we divide the numerator by the denominator and multiply the result by 100:
(2/7) x 100 ≈ 28.57%
Which means, 80/280 represents approximately 28.Day to day, for example, if 80 out of 280 students passed an exam, we can say that approximately 28. 57%. Now, this percentage representation provides a more readily understandable comparison to other proportions. 57% of the students passed.
