You are watching: 1/4 plus 1/8

Rules because that expressions with fractions: Fractions - use the cut “/” between the numerator and also denominator, i.e., for five-hundredths, get in

**5/100**. If you room using blended numbers, be certain to leave a single space between the whole and portion part.

**The cut separates the molecule (number over a fraction line) and also denominator (number below).Mixed numerals**(mixed fractions or combined numbers) write as non-zero integer separated through one room and portion i.e.,

**12/3**(having the same sign). An example of a an adverse mixed fraction:

**-5 1/2**.

**Because cut is both indicators for fraction line and division, we recommended use colon (:) as the operator of department fractions i.e., 1/2 : 3**.

**Decimals (decimal numbers) go into with a decimal point .**and they are immediately converted to fountain - i.e.

**1.45**.

**The colon :**and also slash

**/**is the price of division. Deserve to be used to divide mixed numbers

**12/3 : 43/8**or have the right to be supplied for write facility fractions i.e.

**1/2 : 1/3**.

**An asterisk ***or

**×**is the symbol because that multiplication.

**Plus +**is addition, minus sign

**-**is subtraction and

**()<>**is mathematical parentheses.

**The exponentiation/power price is ^**- because that example:

**(7/8-4/5)^2**= (7/8-4/5)2

**Examples: • adding fractions: 2/4 + 3/4• subtracting fractions: 2/3 - 1/2• multiplying fractions: 7/8 * 3/9• splitting Fractions: 1/2 : 3/4• exponentiation of fraction: 3/5^3• fountain exponents: 16 ^ 1/2• including fractions and also mixed numbers: 8/5 + 6 2/7• dividing integer and also fraction: 5 ÷ 1/2• facility fractions: 5/8 : 2 2/3• decimal to fraction: 0.625• portion to Decimal: 1/4• portion to Percent: 1/8 %• to compare fractions: 1/4 2/3• multiply a fraction by a totality number: 6 * 3/4• square source of a fraction: sqrt(1/16)• reducing or simplifying the portion (simplification) - dividing the numerator and also denominator that a portion by the very same non-zero number - equivalent fraction: 4/22• expression through brackets: 1/3 * (1/2 - 3 3/8)• compound fraction: 3/4 of 5/7• fractions multiple: 2/3 that 3/5• division to uncover the quotient: 3/5 ÷ 2/3The calculator follows well-known rules because that order the operations**. The most common mnemonics because that remembering this order of work are:

**PEMDAS**- Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

**BEDMAS**- Brackets, Exponents, Division, Multiplication, Addition, Subtraction

**BODMAS**- Brackets, that or Order, Division, Multiplication, Addition, Subtraction.

**GEMDAS**- Grouping symbols - brackets (), Exponents, Multiplication, Division, Addition, Subtraction.

**it is in careful, always do multiplication and division**before

**addition and also subtraction**. Part operators (+ and -) and also (* and also /) has the exact same priority and also then must evaluate indigenous left to right.
