7 1/4 - 4 1/2
Fraction figurer
This figurer divides fraction by integer or whole number. To divide fraction by a whole number, we split up the denominator by the whole number. Then simplify the issue to the lowest terms or a mixed number.
The result:
4/1/ii = ii / one = 2
Spelled upshot in words is 2.
How do nosotros solve fractions step past step?
- Divide: four : 2 = ii
Rules for expressions with fractions:
Fractions - utilise a forward slash to divide the numerator by the denominator, i.e., for five-hundredths, enter five/100. If you use mixed numbers, go out a space between the whole and fraction parts.
Mixed numerals (mixed numbers or fractions) keep one space between the integer and
fraction and utilize a forward slash to input fractions i.e., i ii/3 . An example of a negative mixed fraction: -5 one/2.
Because slash is both signs for fraction line and division, utilize a colon (:) as the operator of division fractions i.e., 1/2 : one/three.
Decimals (decimal numbers) enter with a decimal betoken . and they are automatically converted to fractions - i.e. 1.45.
Math Symbols
Symbol | Symbol name | Symbol Significant | Example |

* | asterisk | multiplication | two/3 * 3/4 |
× | times sign | multiplication | 2/three × 5/6 |
: | division sign | sectionalisation | ane/2 : 3 |
/ | division slash | division | i/3 / five |
: | colon | complex fraction | 1/2 : 1/3 |

The calculator follows well-known rules for the guild of operations. The most common mnemonics for remembering this order of operations are:
PEMDAS - Parentheses, Exponents, Multiplication, Sectionalisation, Improver, Subtraction.
BEDMAS - Brackets, Exponents, Partitioning, Multiplication, Addition, Subtraction
BODMAS - Brackets, Of or Gild, Partitioning, Multiplication, Improver, Subtraction.
GEMDAS - Grouping Symbols - brackets (){}, Exponents, Multiplication, Sectionalisation, Addition, Subtraction.
MDAS - Multiplication and Partitioning have the aforementioned precedence over Add-on and Subtraction. The MDAS rule is the order of operations office of the PEMDAS dominion.
Be careful; always exercise multiplication and sectionalization before addition and subtraction. Some operators (+ and -) and (* and /) have the same priority and must evaluate from left to right.
