Calculator subtracting mixed number and fraction
1 3/5 - 5/6 = 2330 ≅ 0.7666667
Spelled result in words is twenty-three thirtieths.Calculation steps
- Conversion a mixed number to a improper fraction: 1 3/5 = 1 35 = 1 · 5 + 35 = 5 + 35 = 85
To find new numerator:
a) Multiply the whole number 1 by the denominator 5. Whole number 1 equally 1 * 55 = 55
b) Add the answer from previous step 5 to the numerator 3. New numerator is 5 + 3 = 8
c) Write previous answer (new numerator 8) over the denominator 5. - Subtract: 85 - 56 = 8 · 65 · 6 - 5 · 56 · 5 = 4830 - 2530 = 48 - 2530 = 2330
The common denominator you can calculate as the least common multiple of the both denominators - LCM(5, 6) = 30. The fraction result cannot be further simplified by cancelling.
In words - eight fifths minus five sixths = twenty-three thirtieths.

Rules for expressions with fractions:
Fractions - use the slash “/” between the numerator and denominator, i.e. for five-hundredths enter 5/100. If you are using mixed numbers be sure to leave a single space between the whole number and fraction part.The slash separates the numerator (number above a fraction line) and denominator (number below).
Mixed numerals (mixed fractions or mixed numbers) write as non-zero integer separated by one space and fraction i.e., 1 2/3 (having the same sign). An example of a negative mixed fraction: -5 1/2.
Because slash is both signs for fraction line and division, we recommended use colon (:) as operator of division fractions i.e., 1/2 : 3.
Decimals (decimal numbers) enter with a decimal point . and they are automatically converted to fractions - i.e. 1.45.
Colon : and slash / is the symbol of division. Can be used to divide mixed numbers 1 2/3 : 4 3/8 or can be used for write complex fractions i.e. 1/2 : 1/3.
An asterisk * or × is the symbol for multiplication.
Plus + is addition, minus sign - is subtraction and ()[] is mathematical parentheses.
The exponentiation/power symbol is ^ - for example: (7/8-4/5)^2 = (7/8-4/5)2

Calculator follows well-known rules for order of operations. Most common mnemonics for remembering this order of operations are:
PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction
BODMAS - Brackets, Of or Order, Division, Multiplication, Addition, Subtraction.
GEMDAS - Grouping Symbols - brackets (){}, Exponents, Multiplication, Division, Addition, Subtraction.
Be careful, always do multiplication and division before addition and subtraction. Some operators (+ and -) and (* and /) has the same priority and then must evaluate from left to right.
