28 is the simplest form
To simplify 28 / 35, you divide by the GCF of 28 and 35. The GCF is 7, so 28 / 35 / 7 = 4 / 5.
The given expression is 4 - √28. Since 28 contains a perfect square factor, we can simplify √28 to get: 4 - √(4 * 7) = 4 - √(2² * 7) = 4 - 2√7
12/28 = 3/7 = 0.428571428
If we want to "simplify" 28%, we can start by writing it as 28/100ths, which is 7/25ths (7/25). That's about the best we can do. As 28% is less than one, it cannot be written as a mixed number.
