Calculator subtracting two 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.
7 1/2 - 5 3/4 = 7/ = 1 3/ = 1.75Spelled result in words is one and three quarters (or seven quarters).
- Conversion a mixed number 7 1/ to a improper fraction: 7 1/2 = 7 1/ = 7 · 2 + 1/ = 14 + 1/ = 15/
To find a new numerator:
a) Multiply the whole number 7 by the denominator 2. Whole number 7 equally 7 * 2/ = 14/
b) Add the answer from previous step 14 to the numerator 1. New numerator is 14 + 1 = 15
c) Write a previous answer (new numerator 15) over the denominator 2.
Seven and one half is fifteen halfs
- Conversion a mixed number 5 3/ to a improper fraction: 5 3/4 = 5 3/ = 5 · 4 + 3/ = 20 + 3/ = 23/
To find a new numerator:
a) Multiply the whole number 5 by the denominator 4. Whole number 5 equally 5 * 4/ = 20/
b) Add the answer from previous step 20 to the numerator 3. New numerator is 20 + 3 = 23
c) Write a previous answer (new numerator 23) over the denominator 4.
Five and three quarters is twenty-three quarters
- Subtract: 15/ - 23/ = 15 · 2/ - 23/ = 30/ - 23/ = 30 - 23/ = 7/
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(2, 4) = 4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 4 = 8. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - fifteen halfs minus twenty-three quarters = seven quarters.
