To add fractions and whole numbers, convert a whole number into a fraction with the same denominator as the fraction that needs to be added. Add up the numerators and keep the denominator the same.
To add whole numbers and fractions, the whole number must also be turned into a fraction to combine the two. For example, if the problem to be solved with 3/4 + 7, the 7 would become a fraction by representing it as 7/1. Any whole number can be easily turned into a frac...
To multiply fractions with whole numbers, convert the mixed fractions to improper fractions, then multiply the numerators and denominators. Convert the answer back to mixed fractions if necessary.
Subtract fractions with whole numbers by converting the mixed fractions to improper fractions, finding the lowest common denominator and subtracting the numerators. Convert the result back to mixed fractions and simplify, if necessary.
A fraction is converted to a percentage by first expressing the fraction with a denominator of 100, then writing the numerator with a percent sign behind it. Some fractions can be easily converted if basic ratio equivalents are known.
The top number in a fraction is called a numerator. The bottom number is called a denominator. The line that separates them can be horizontal or vertical.
A whole number and a mixed number are simplified by first expressing the sum as a fraction with the same denominator as the proper fraction portion of the mixed number, and then simplifying that fraction if possible. The resulting number is an improper fraction. To conv...
