A mixed number is a number composed of an integer (whole) number and a proper fraction, one that has a numerator less than the denominator. Example 2 1/3 =2+ 1/3. 2 is the integer part, and 1/3 is the proper fraction part. Certain fractions can be simplified further because the numerator and denominator share a (common) factor. By cancelling the common factor in the numerator with the factor in the denominator, one gets a fraction with smaller numerator and denominator. For example the percentage you provide 0.15% can be converted to 15/10000. Since 15 and 1000 are both multiples of 5, the number 5 is a common factor in both. 15=5*3, and 10000=5*2000 Cancel the two 5 (simplifying by 5) in numerator and denominator leaves 3/2000. Thus 0.15%= 0.15/100=0.0015=3/200 I hope that this makes sense to you.
