The slash separates the numerator (number above a fraction line) and denominator (number below). If you are using mixed numbers, be sure to leave a single space between the whole and fraction part. Rules for expressions with fractions: Fractions - simply use a forward slash between the numerator and denominator, i.e., for five-hundredths, enter 5/100. In other words - fifteen quarters multiplied by twelve fifths = nine. In the following intermediate step, cancel by a common factor of 20 gives 9 / 1. Result fraction keep to lowest possible denominator GCD(180, 20) = 20. Multiply both numerators and denominators. New numerator is 10 + 2 = 12Ĭ) Write a previous answer (new numerator 12) over the denominator 5. Whole number 2 equally 2 * 5 / 5 = 10 / 5ī) Add the answer from previous step 10 to the numerator 2. Conversion a mixed number 2 2 / 5 to a improper fraction: 2 2/5 = 2 2 / 5 = 2 Ī) Multiply the whole number 2 by the denominator 5.
Three and three quarters is fifteen quarters New numerator is 12 + 3 = 15Ĭ) Write a previous answer (new numerator 15) over the denominator 4. Whole number 3 equally 3 * 4 / 4 = 12 / 4ī) Add the answer from previous step 12 to the numerator 3. Conversion a mixed number 3 3 / 4 to a improper fraction: 3 3/4 = 3 3 / 4 = 3 Ī) Multiply the whole number 3 by the denominator 4.
