You are watching: 3/4 minus 1/8
Divide: 3/4 : 1/8 = 3/4 · 8/1 = 3 · 8/4 · 1 = 24/4 = 4 · 6 /4 · 1 = 6 dividing two fountain is the exact same as multiply the very first fraction by the reciprocal worth of the 2nd fraction. The first sub-step is to find the mutual (reverse the numerator and also denominator, reciprocal of 1/8 is 8/1) the the 2nd fraction. Next, main point the 2 numerators. Then, main point the two denominators. In the complying with intermediate step, publication by a usual factor that 4 provides 6/1. In various other words - three quarters divided by one eighth = six.
Rules because that expressions with fractions: Fractions - merely use a forward slash between the numerator and denominator, i.e., because that five-hundredths, enter 5/100. If you space using combined numbers, be sure to leave a solitary space between the entirety and fraction part.The slash separates the numerator (number over a fraction line) and denominator (number below).Mixed numerals (mixed fractions or mixed numbers) compose as essence separated through 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 portion line and also division, us recommended use colon (:) together the operator of department fractions i.e., 1/2 : 3.Decimals (decimal numbers) enter with a decimal allude . and they are automatically converted to fractions - i.e. 1.45.The colon : and also slash / is the prize of division. Have the right to be supplied to divide mixed numbers 12/3 : 43/8 or have the right to be supplied for write complicated fractions i.e. 1/2 : 1/3.An asterisk * or × is the symbol for multiplication.Plus + is addition, minus sign - is subtraction and ()<> is math parentheses.The exponentiation/power prize is ^ - because that example: (7/8-4/5)^2 = (7/8-4/5)2
Examples: • adding fractions: 2/4 + 3/4• individually fractions: 2/3 - 1/2• multiplying fractions: 7/8 * 3/9• dividing Fractions: 1/2 : 3/4• indexes of fraction: 3/5^3• fractional exponents: 16 ^ 1/2• adding fractions and mixed numbers: 8/5 + 6 2/7• splitting integer and fraction: 5 ÷ 1/2• complex fractions: 5/8 : 2 2/3• decimal to fraction: 0.625• fraction to Decimal: 1/4• portion to Percent: 1/8 %• to compare fractions: 1/4 2/3• multiplying a portion by a totality number: 6 * 3/4• square root of a fraction: sqrt(1/16)• reducing or simple the portion (simplification) - splitting the numerator and also denominator of a fraction by the exact same non-zero number - identical 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 famous rules because that order that operations. The most usual mnemonics for remembering this order of to 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 signs - base (), Exponents, Multiplication, Division, Addition, Subtraction. be careful, constantly do multiplication and also division prior to addition and also subtraction. Part operators (+ and -) and also (* and also /) has actually the same priority and also then have to evaluate native left to right.
