You are watching: 3/5 divided by 2
conversion a blended number 2 1/2 to a wrong fraction: 2 1/2 = 2 1/2 = 2 · 2 + 1/2 = 4 + 1/2 = 5/2To find new numerator:a) multiply the entirety number 2 by the denominator 2. Totality number 2 same 2 * 2/2 = 4/2b) add the answer indigenous previous action 4 to the numerator 1. Brand-new numerator is 4 + 1 = 5c) compose a previous price (new molecule 5) end the denominator 2.Two and also one half is 5 halfs Divide: 3/5 : 5/2 = 3/5 · 2/5 = 3 · 2/5 · 5 = 6/25 dividing two fractions is the same as multiplying the an initial fraction through the reciprocal value of the second fraction. The first sub-step is to discover the reciprocal (reverse the numerator and also denominator, mutual of 5/2 is 2/5) of the second fraction. Next, multiply the 2 numerators. Then, multiply the two denominators. In the following intermediate step, the fraction result can not be further simplified by canceling.In words - three fifths divided by five halfs = six twenty-fifths.
Rules because that expressions through fractions: Fractions - usage the slash “/” in between the numerator and also denominator, i.e., for five-hundredths, get in 5/100. If you room using blended numbers, be sure to leave a solitary space in between the totality and fraction part.The slash separates the molecule (number over a portion line) and denominator (number below).Mixed numerals (mixed fractions or mixed numbers) write as non-zero creature separated through one room and portion i.e., 12/3 (having the exact same sign). An example of a negative mixed fraction: -5 1/2.Because slash is both indications for portion line and also division, we recommended use colon (:) together the operator of division fractions i.e., 1/2 : 3.Decimals (decimal numbers) go into with a decimal allude . and also they are instantly converted to fountain - i.e. 1.45.The colon : and slash / is the symbol of division. Have the right to be provided to divide mixed numbers 12/3 : 43/8 or deserve to be supplied 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• indices of fraction: 3/5^3• fountain exponents: 16 ^ 1/2• including fractions and also mixed numbers: 8/5 + 6 2/7• splitting integer and 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• multiply a fraction by a entirety number: 6 * 3/4• square source of a fraction: sqrt(1/16)• to reduce or simplifying the fraction (simplification) - dividing the numerator and also denominator of a fraction by the exact same non-zero number - tantamount fraction: 4/22• expression with brackets: 1/3 * (1/2 - 3 3/8)• compound fraction: 3/4 that 5/7• fountain multiple: 2/3 the 3/5• divide to uncover the quotient: 3/5 ÷ 2/3The calculator follows famous rules for order that operations. The most typical mnemonics for remembering this bespeak of 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.

GEMDAS - Grouping symbols - brackets (), Exponents, Multiplication, Division, Addition, Subtraction. it is in careful, always do multiplication and division before addition and subtraction. Part operators (+ and also -) and also (* and /) has actually the same priority and also then have to evaluate from left come right.
