Calculator subtracting mixed number and 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 - 5/6 = 23/ ≅ 0.7666667Spelled result in words is twenty-three thirtieths.
- Conversion a mixed number 1 3/ to a improper fraction: 1 3/5 = 1 3/ = 1 · 5 + 3/ = 5 + 3/ = 8/
To find new numerator:
a) Multiply the whole number 1 by the denominator 5. Whole number 1 equally 1 * 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
- Subtract: 8/ - 5/ = 8 · 6/ - 5 · 5/ = 48/ - 25/ = 48 - 25/ = 23/
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, 6) = 30. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 6 = 30. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - eight fifths minus five sixths = twenty-three thirtieths.
