How Do You Understand Fractions And Percentages?
A fraction is a number that expresses part of a group. A percentage is a number that expresses part of a group of 100. Here is some introductory material about both. Remember that the number above the line is the numerator, and the number below the line is the denominator. In the fraction, ½, the 1 is the numerator, and the 2 is the denominator. Add two fractions whose denominators are the same by adding their numerators. For example, 3/5 + 1/5 = 4/5. Subtract two fractions whose denominators are the same by subtracting their numerators: 3/5 – 1/5 = 2/5. To add or subtract two fractions whose denominators are different, first convert one or both fractions so that they have the same, or “common,” denominator. Convert a fraction by multiplying both its numerator and denominator by the same non-zero number. If you want to add 1/5 and 1/10 together, then convert 1/5 by multiplying both the 1 and the 5 by 2: 1/5 X 2/2 = 2/10. Next, you can add 2/10 + 1/10 = 3/10. Multiply two fractions by f
