### 8/5 + 6 2/7 = 276/35 = 7 31/35 ≅ 7.8857143

Spelled an outcome in words is 2 hundred seventy-six thirty-fifths (or seven and thirty-one thirty-fifths).switch a combined number 6 2/7 come a wrong fraction: 6 2/7 = 6 2/7 = 6 · 7 + 2/7 = 42 + 2/7 = 44/7To find brand-new numerator:a) main point the entirety number 6 by the denominator 7. Entirety number 6 same 6 * 7/7 = 42/7b) add the answer native previous step 42 to the molecule 2. New numerator is 42 + 2 = 44c) compose a previous prize (new numerator 44) over the denominator 7.Six and two saturday is forty-four saturday

Rules for expressions v fractions: Fractions - usage the slash “/” between the numerator and also denominator, i.e., for five-hundredths, get in

**5/100**. If you space using combined numbers, be sure to leaving a single space between the entirety and fraction part.

**The cut separates the numerator (number above a portion line) and also denominator (number below).Mixed numerals**(mixed fractions or mixed numbers) create as non-zero integer separated through one an are and portion i.e.,

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

**-5 1/2**.

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

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

**1.45**.

**The colon :**and also slash

**/**is the symbol of division. Can be used to divide blended numbers

**12/3 : 43/8**or can be offered 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 mathematics parentheses.

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

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

**The calculator follows famous rules for order that operations**. The most typical mnemonics for remembering this order of work 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 signs - brackets (), Exponents, Multiplication, Division, Addition, Subtraction.

**be careful, always do multiplication and division**before

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