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