# Calculator sum mixed number and an improper fraction

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 3/5 + 11/5 = 19/5 = 3 4/5 = 3.8

Spelled result in words is three and four fifths (or nineteen fifths).### Calculation steps

- Conversion a mixed number 1 3/5 to a improper fraction: 1 3/5 = 1 3/5 = 1 · 5 + 3/5 = 5 + 3/5 = 8/5

To find new numerator:

a) Multiply the whole number 1 by the denominator 5. Whole number 1 equally 1 * 5/5 = 5/5

b) Add the answer from previous step 5 to the numerator 3. New numerator is 5 + 3 = 8

c) Write a previous answer (new numerator 8) over the denominator 5.

One and three fifths is eight fifths - Add: 8/5 + 11/5 = 8 + 11/5 = 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 the 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 next intermediate step the fraction result cannot be further simplified by canceling.

In words - eight fifths plus eleven fifths = nineteen fifths.
