![]() Rules for expressions with fractions: Fractions - use a forward slash to divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100. ![]() In other words - eleven halfs minus five quarters is seventeen quarters. In the following intermediate step, it cannot further simplify the fraction result by canceling. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 4 = 8. The common denominator you can calculate as the least common multiple of both denominators - LCM(2, 4) = 4. It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. New numerator is 4 + 1 = 5Ĭ) Write a previous answer (new numerator 5) over the denominator 4. Whole number 1 equally 1 * 4 / 4 = 4 / 4ī) Add the answer from the previous step 4 to the numerator 1. Conversion a mixed number 1 1 / 4 to a improper fraction: 1 1/4 = 1 1 / 4 = 1 Ī) Multiply the whole number 1 by the denominator 4. ![]() In other words - twenty-five eighths plus nineteen eighths is eleven halfs. In the following intermediate step, cancel by a common factor of 4 gives 11 / 2. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 8 = 64. The common denominator you can calculate as the least common multiple of both denominators - LCM(8, 8) = 8. Two and three eighths is nineteen eighths. New numerator is 16 + 3 = 19Ĭ) Write a previous answer (new numerator 19) over the denominator 8. Whole number 2 equally 2 * 8 / 8 = 16 / 8ī) Add the answer from the previous step 16 to the numerator 3. Conversion a mixed number 2 3 / 8 to a improper fraction: 2 3/8 = 2 3 / 8 = 2 Ī) Multiply the whole number 2 by the denominator 8.Three and one eighth is twenty-five eighths. New numerator is 24 + 1 = 25Ĭ) Write a previous answer (new numerator 25) over the denominator 8. Whole number 3 equally 3 * 8 / 8 = 24 / 8ī) Add the answer from the previous step 24 to the numerator 1. Conversion a mixed number 3 1 / 8 to a improper fraction: 3 1/8 = 3 1 / 8 = 3 Ī) Multiply the whole number 3 by the denominator 8.
