# Calculator addition of three mixed numbers

The calculator performs basic and advanced operations with mixed numbers, fractions, integers, decimals. Mixed fractions are also called mixed numbers. A mixed fraction is a whole number and a proper fraction combined, i.e. one and three-quarters. The calculator evaluates the expression or solves the equation with step-by-step calculation progress information. Solve problems with two or more mixed numbers fractions in one expression.

### 1 3/8 + 6 11/13 + 5 7/8 = 733/52 = 14 5/52 ≅ 14.0961538

Spelled result in words is fourteen and five fifty-seconds (or seven hundred thirty-three fifty-seconds).### Calculation steps

- Conversion a mixed number 1 3/8 to a improper fraction: 1 3/8 = 1 3/8 = 1 · 8 + 3/8 = 8 + 3/8 = 11/8

To find new numerator:

a) Multiply the whole number 1 by the denominator 8. Whole number 1 equally 1 * 8/8 = 8/8

b) Add the answer from previous step 8 to the numerator 3. New numerator is 8 + 3 = 11

c) Write a previous answer (new numerator 11) over the denominator 8.

One and three eighths is eleven eighths - Conversion a mixed number 6 11/13 to a improper fraction: 6 11/13 = 6 11/13 = 6 · 13 + 11/13 = 78 + 11/13 = 89/13

To find new numerator:

a) Multiply the whole number 6 by the denominator 13. Whole number 6 equally 6 * 13/13 = 78/13

b) Add the answer from previous step 78 to the numerator 11. New numerator is 78 + 11 = 89

c) Write a previous answer (new numerator 89) over the denominator 13.

Six and eleven thirteenths is eighty-nine thirteenths - Add: 11/8 + 89/13 = 11 · 13/8 · 13 + 89 · 8/13 · 8 = 143/104 + 712/104 = 143 + 712/104 = 855/104

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(8, 13) = 104. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 13 = 104. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - eleven eighths plus eighty-nine thirteenths = eight hundred fifty-five one-hundred fourths. - Conversion a mixed number 5 7/8 to a improper fraction: 5 7/8 = 5 7/8 = 5 · 8 + 7/8 = 40 + 7/8 = 47/8

To find new numerator:

a) Multiply the whole number 5 by the denominator 8. Whole number 5 equally 5 * 8/8 = 40/8

b) Add the answer from previous step 40 to the numerator 7. New numerator is 40 + 7 = 47

c) Write a previous answer (new numerator 47) over the denominator 8.

Five and seven eighths is forty-seven eighths - Add: the result of step No. 3 + 47/8 = 855/104 + 47/8 = 855/104 + 47 · 13/8 · 13 = 855/104 + 611/104 = 855 + 611/104 = 1466/104 = 2 · 733/2 · 52 = 733/52

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(104, 8) = 104. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 104 × 8 = 832. In the next intermediate step, , cancel by a common factor of 2 gives 733/52.

In words - eight hundred fifty-five one-hundred fourths plus forty-seven eighths = seven hundred thirty-three fifty-seconds.
