You are watching: 12*7=
7/12 / 3/10 = 35/18 = 1 17/18 ≅ 1.9444444Spelled an outcome in native is thirty-five eighteenths (or one and also seventeen eighteenths).
Divide: 7/12 : 3/10 = 7/12 · 10/3 = 7 · 10/12 · 3 = 70/36 = 2 · 35 /2 · 18 = 35/18 dividing two fractions is the same as multiplying the very first fraction by the reciprocal worth of the 2nd fraction. The very first sub-step is to uncover the mutual (reverse the numerator and also denominator, reciprocal of 3/10 is 10/3) that the second fraction. Next, main point the two numerators. Then, multiply the 2 denominators. In the following intermediate step, , cancel by a usual factor of 2 offers 35/18. In native - seven twelfths divided by three tenths = thirty-five eighteenths.
Rules because that expressions through fractions: Fractions - usage the slash “/” in between the numerator and denominator, i.e., because that five-hundredths, get in 5/100. If you are using combined numbers, be certain to leave a solitary space in between the entirety and fraction part.The cut separates the numerator (number over a portion line) and denominator (number below).Mixed numerals (mixed fountain or mixed numbers) create as non-zero creature separated by one room and fraction i.e., 12/3 (having the same sign). An example of a negative mixed fraction: -5 1/2.Because slash is both indications for fraction line and also division, we recommended usage colon (:) as the operator of department fractions i.e., 1/2 : 3.Decimals (decimal numbers) go into with a decimal suggest . and also they are instantly converted to fractions - i.e. 1.45.The colon : and also slash / is the price of division. Can be provided to divide combined 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 for multiplication.Plus + is addition, minus sign - is subtraction and also ()<> is mathematical parentheses.The exponentiation/power prize is ^ - for example: (7/8-4/5)^2 = (7/8-4/5)2
Examples: • including fractions: 2/4 + 3/4• subtracting fractions: 2/3 - 1/2• multiply fractions: 7/8 * 3/9• splitting Fractions: 1/2 : 3/4• exponentiation of fraction: 3/5^3• fractional exponents: 16 ^ 1/2• adding fractions and mixed numbers: 8/5 + 6 2/7• splitting integer and also fraction: 5 ÷ 1/2• facility fractions: 5/8 : 2 2/3• decimal to fraction: 0.625• portion to Decimal: 1/4• fraction to Percent: 1/8 %• comparing fractions: 1/4 2/3• multiplying a fraction by a entirety number: 6 * 3/4• square root of a fraction: sqrt(1/16)• reduce or simple the fraction (simplification) - splitting the numerator and also denominator that a fraction by the very same non-zero number - indistinguishable fraction: 4/22• expression with brackets: 1/3 * (1/2 - 3 3/8)• compound fraction: 3/4 of 5/7• fountain multiple: 2/3 the 3/5• division to uncover the quotient: 3/5 ÷ 2/3The calculator follows renowned 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, of or Order, Division, Multiplication, Addition, Subtraction.

GEMDAS - Grouping signs - brackets (), Exponents, Multiplication, Division, Addition, Subtraction. it is in careful, constantly do multiplication and also division prior to addition and also subtraction. Some operators (+ and also -) and (* and /) has actually the exact same priority and also then should evaluate native left to right.
