You are watching: 1 1/4 divided by 3
Divide: 1/4 : 3 = 1/4 · 1/3 = 1 · 1/4 · 3 = 1/12 dividing two fractions is the very same as multiplying the very first fraction by the reciprocal worth of the second fraction. The very first sub-step is to find the mutual (reverse the numerator and denominator, mutual of 3/1 is 1/3) of the 2nd fraction. Next, multiply the two numerators. Then, main point the 2 denominators. In the following intermediate step, the fraction result can not be further simplified by canceling.In various other words - one quarter split by three = one twelfth.
Rules for expressions with fractions: Fractions - just use a front slash in between the numerator and denominator, i.e., for five-hundredths, get in 5/100. If you are using blended numbers, be certain to leaving a solitary space between the entirety and portion part.The cut separates the molecule (number over a portion line) and also denominator (number below).Mixed numerals (mixed fractions or mixed numbers) create as integer separated by one room and portion i.e., 12/3 (having the exact same sign). An example of a an unfavorable mixed fraction: -5 1/2.Because cut is both signs for fraction line and division, we recommended usage colon (:) as the operator of division fractions i.e., 1/2 : 3.Decimals (decimal numbers) enter with a decimal allude . and also they are instantly converted to fractions - i.e. 1.45.The colon : and slash / is the price of division. Deserve to be offered to divide blended numbers 12/3 : 43/8 or have the right to be used for write complex fractions i.e. 1/2 : 1/3.An asterisk * or × is the symbol for multiplication.Plus + is addition, minus authorize - is subtraction and ()<> is mathematics parentheses.The exponentiation/power price is ^ - because that example: (7/8-4/5)^2 = (7/8-4/5)2
Examples: • adding 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 also 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• portion to Percent: 1/8 %• compare fractions: 1/4 2/3• multiply a portion by a entirety number: 6 * 3/4• square root of a fraction: sqrt(1/16)• reducing or simplifying the portion (simplification) - separating the numerator and also denominator that a fraction by the exact same non-zero number - equivalent fraction: 4/22• expression v brackets: 1/3 * (1/2 - 3 3/8)• link fraction: 3/4 that 5/7• fractions multiple: 2/3 the 3/5• divide to find the quotient: 3/5 ÷ 2/3The calculator follows renowned rules for order the operations. The most usual mnemonics for remembering this stimulate of operations are: PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction BODMAS - Brackets, of or Order, Division, Multiplication, Addition, Subtraction.
