You are watching: -2 divided by -1

Divide: 12 : 1/2 = 12/1 · 2/1 = 12 · 2/1 · 1 = 24/1 = 24 splitting two fractions is the exact same as multiply the an initial fraction by the reciprocal worth of the 2nd fraction. The first sub-step is to uncover the reciprocal (reverse the numerator and denominator, reciprocal of 1/2 is 2/1) of the 2nd fraction. Next, multiply the 2 numerators. Then, main point the 2 denominators.In other words - twelve split by one fifty percent = twenty-four.

Rules for expressions v fractions: Fractions - simply use a forward slash in between the numerator and denominator, i.e., for five-hundredths, go into

**5/100**. If you room using mixed numbers, be certain to leaving a solitary space between the totality and fraction part.

**The slash separates the molecule (number over a portion line) and also denominator (number below).Mixed numerals**(mixed fountain or blended numbers) create as creature separated by one room and fraction i.e.,

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

**-5 1/2**.

**Because slash is both signs for portion line and also division, we recommended usage colon (:) together the operator of department fractions i.e., 1/2 : 3**.

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

**1.45**.

**The colon :**and slash

**/**is the symbol of division. Deserve to be provided to divide mixed numbers

**12/3 : 43/8**or have the right to 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 also

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

**The exponentiation/power symbol is ^**- for example:

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

**Examples: • including fractions: 2/4 + 3/4• individually fractions: 2/3 - 1/2• multiply fractions: 7/8 * 3/9• splitting Fractions: 1/2 : 3/4• indexes of fraction: 3/5^3• spring exponents: 16 ^ 1/2• adding fractions and mixed numbers: 8/5 + 6 2/7• separating integer and fraction: 5 ÷ 1/2• complex fractions: 5/8 : 2 2/3• decimal come fraction: 0.625• portion to Decimal: 1/4• portion to Percent: 1/8 %• to compare fractions: 1/4 2/3• multiplying a fraction by a whole number: 6 * 3/4• square source of a fraction: sqrt(1/16)• reduce or simplifying the fraction (simplification) - separating the numerator and also denominator that a portion by the very same non-zero number - indistinguishable fraction: 4/22• expression v brackets: 1/3 * (1/2 - 3 3/8)• compound fraction: 3/4 that 5/7• fractions multiple: 2/3 of 3/5• division to discover the quotient: 3/5 ÷ 2/3The calculator follows renowned rules because that order of operations**. The most typical mnemonics for remembering this stimulate of to 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.

**be careful, always do multiplication and also division**prior to

**addition and subtraction**. Part operators (+ and -) and also (* and /) has actually the same priority and also then need to evaluate native left come right.
