You are watching: 1 and 1/2 divided by 2
Divide: 1/2 : 2 = 1/2 · 1/2 = 1 · 1/2 · 2 = 1/4 Dividing 2 fractions is the very same as multiplying the first fractivity by the reciprocal worth of the second fractivity. The initially sub-action is to uncover the reciprocal (reverse the numerator and also denominator, reciprocal of 2/1 is 1/2) of the second fractivity. Next off, multiply the two numerators. Then, multiply the 2 denominators. In the following intermediate step, the fraction outcome cannot be better streamlined by canceling.In words - one fifty percent split by 2 = one quarter.
Rules for expressions with fractions: Fractions - use the slash “/” between the numerator and also denominator, i.e., for five-hundredths, enter 5/100. If you are using combined numbers, be sure to leave a single area between the entirety and also fraction component.The slash separates the numerator (number over a portion line) and denominator (number below).Mixed numerals (mixed fractions or blended numbers) create as non-zero integer separated by one area and fractivity i.e., 12/3 (having actually the very same sign). An example of an unfavorable combined fraction: -5 1/2.Due to the fact that slash is both indications for fraction line and division, we recommfinished usage colon (:) as the operator of department fractions i.e., 1/2 : 3.Decimals (decimal numbers) enter through a decimal allude . and also they are immediately converted to fractions - i.e. 1.45.The colon : and slash / is the symbol of division. Can be offered to divide blended numbers 12/3 : 43/8 or have the right to be offered for write facility fractions i.e. 1/2 : 1/3.An astehazard * or × is the symbol for multiplication.Plus + is enhancement, minus authorize - is subtractivity and also ()<> is mathematical 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• subtracting fractions: 2/3 - 1/2• multiplying fractions: 7/8 * 3/9• splitting Fractions: 1/2 : 3/4• exponentiation of fraction: 3/5^3• fractional exponents: 16 ^ 1/2• including fractions and also blended numbers: 8/5 + 6 2/7• dividing integer and also fraction: 5 ÷ 1/2• complex fractions: 5/8 : 2 2/3• decimal to fraction: 0.625• Fractivity to Decimal: 1/4• Fractivity to Percent: 1/8 %• comparing fractions: 1/4 2/3• multiplying a fraction by a totality number: 6 * 3/4• square root of a fraction: sqrt(1/16)• reducing or simplifying the fractivity (simplification) - separating the numerator and denominator of a fraction by the very same non-zero number - tantamount fraction: 4/22• expression through brackets: 1/3 * (1/2 - 3 3/8)• compound fraction: 3/4 of 5/7• fractions multiple: 2/3 of 3/5• divide to find the quotient: 3/5 ÷ 2/3The calculator complies with famous rules for order of operations. The many widespread mnemonics for remembering this order of operations are: PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtractivity. BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction BODMAS - Brackets, Of or Order, Division, Multiplication, Addition, Subtraction.

GEMDAS - Grouping Symbols - brackets (), Exponents, Multiplication, Division, Addition, Subtraction. Be cautious, constantly carry out multiplication and division prior to enhancement and also subtraction. Some operators (+ and -) and (* and also /) has the exact same priority and also then have to evaluate from left to best.
