You are watching: 1/2 plus 1/4
Divide: 1/4 : 1/2 = 1/4 · 2/1 = 1 · 2/4 · 1 = 2/4 = 2 · 1 /2 · 2 = 1/2 dividing two fractions is the very same as multiply the first fraction by the reciprocal worth of the 2nd fraction. The first sub-step is to uncover the reciprocal (reverse the numerator and also denominator, reciprocal of 1/2 is 2/1) the the 2nd fraction. Next, main point the 2 numerators. Then, main point the 2 denominators. In the following intermediate step, release by a common factor of 2 offers 1/2. In other words - one quarter separated by one half = one half.
Rules for expressions through fractions: Fractions - usage the slash “/” in between the numerator and also denominator, i.e., for five-hundredths, go into 5/100. If you are using mixed numbers, be sure to leaving a single space in between the totality and portion part.The slash separates the molecule (number above a fraction line) and denominator (number below).Mixed numerals (mixed fractions or blended numbers) write as non-zero creature separated by one an are and portion i.e., 12/3 (having the same sign). An instance of a negative mixed fraction: -5 1/2.Because slash is both indications for fraction line and division, us recommended use colon (:) together the operator of division fractions i.e., 1/2 : 3.Decimals (decimal numbers) enter with a decimal allude . and they are instantly converted to fractions - i.e. 1.45.The colon : and slash / is the prize of division. Have the right to be used 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 asterisk * or × is the symbol for multiplication.Plus + is addition, minus sign - is subtraction and also ()<> is math 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• individually fractions: 2/3 - 1/2• multiplying fractions: 7/8 * 3/9• splitting Fractions: 1/2 : 3/4• exponentiation of fraction: 3/5^3• fountain exponents: 16 ^ 1/2• adding fractions and mixed numbers: 8/5 + 6 2/7• dividing integer and also fraction: 5 ÷ 1/2• complicated fractions: 5/8 : 2 2/3• decimal to fraction: 0.625• portion to Decimal: 1/4• portion to Percent: 1/8 %• comparing fractions: 1/4 2/3• multiplying a fraction by a entirety number: 6 * 3/4• square source of a fraction: sqrt(1/16)• to reduce or simple the portion (simplification) - splitting the numerator and denominator the a fraction by the very same non-zero number - equivalent fraction: 4/22• expression with brackets: 1/3 * (1/2 - 3 3/8)• link fraction: 3/4 that 5/7• fountain multiple: 2/3 the 3/5• divide to find the quotient: 3/5 ÷ 2/3The calculator follows popular rules for order that 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, the or Order, Division, Multiplication, Addition, Subtraction.

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