This calculator adds two fractions. When fractions have different denominators, firstly convert all fractions to lớn common denominator. Find Least Common Denominator (LCD) or simple multiply all denominators to lớn find common denominator. When all denominators are same, simply địa chỉ cửa hàng the numerators and place the result over the common denominator. Then simplify the result lớn the lowest terms or a mixed number.

Result:

2/3 + ba phần tư = 17/12 = 1 5/12 ≅ 1.4166667

Spelled result in words is seventeen twelfths (or one and five twelfths).
Rules for expressions with fractions: Fractions - use a forward slash to lớn divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100. If you use mixed numbers, leave a space between the whole and fraction parts.Mixed numerals (mixed numbers or fractions) keep one space between the integer andfraction and use a forward slash to input đầu vào fractions i.e., 12/3 . An example of a negative mixed fraction: -5 1/2.Because slash is both signs for fraction line & division, use a colon (:) as the operator of division fractions i.e., 50% : 1/3.Decimals (decimal numbers) enter with a decimal point . và they are automatically converted to fractions - i.e. 1.45.

The calculator follows well-known rules for the order of operations
. The 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.

MDAS - Multiplication và Division have the same precedence over Addition và Subtraction. The MDAS rule is the order of operations part of the PEMDAS rule. Be careful; always do multiplication & division before addition và subtraction. Some operators (+ & -) and (* và /) has the same priority & then must evaluate from left to right.
