Result: 15 3/5 - 11 4/5 = 19/ 5 = 3 4/ 5 = 3.8 Spelled result in words is nineteen fifths (or three and four fifths).
How do you solve fractions step by step? Conversion a mixed number 15 3/ 5 to a improper fraction: 15 3/5 = 15 3/ 5 = 15 · 5 + 3/ 5 = 75 + 3/ 5 = 78/ 5
To find a new numerator: a) Multiply the whole number 15 by the denominator 5. Whole number 15 equally 15 * 5/ 5 = 75/ 5
b) Add the answer from previous step 75 to the numerator 3. New numerator is 75 + 3 = 78 c) Write a previous answer (new numerator 78) over the denominator 5.
Fifteen and three fifths is seventy-eight fifths Conversion a mixed number 11 4/ 5 to a improper fraction: 11 4/5 = 11 4/ 5 = 11 · 5 + 4/ 5 = 55 + 4/ 5 = 59/ 5
To find a new numerator: a) Multiply the whole number 11 by the denominator 5. Whole number 11 equally 11 * 5/ 5 = 55/ 5
b) Add the answer from previous step 55 to the numerator 4. New numerator is 55 + 4 = 59 c) Write a previous answer (new numerator 59) over the denominator 5.
Eleven and four fifths is fifty-nine fifths Subtract: 78/ 5 - 59/ 5 = 78 - 59/ 5 = 19/ 5
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 5) = 5. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 5 = 25. In the following intermediate step, it cannot further simplify the fraction result by canceling. In other words - seventy-eight fifths minus fifty-nine fifths = nineteen fifths.
