You are watching: What is one half times one half
2 1/2 = 2 1/2 = 2 · 2 + 1/2 = 4 + 1/2 = 5/2 = 2 1/2 = 2.5Spelled result in native is five halfs (or two and one half).
switch a mixed number 2 1/2 come a improper fraction: 2 1/2 = 2 1/2 = 2 · 2 + 1/2 = 4 + 1/2 = 5/2To find a brand-new numerator:a) main point the entirety number 2 through the denominator 2. Totality number 2 equally 2 * 2/2 = 4/2b) include the answer native previous action 4 to the numerator 1. Brand-new numerator is 4 + 1 = 5c) write a previous answer (new molecule 5) end the denominator 2.Two and also one half is 5 halfs
Rules for expressions with fractions: Fractions - merely use a front slash in between the numerator and denominator, i.e., for five-hundredths, enter 5/100. If you are using blended numbers, be certain to leaving a single space between the whole and fraction part.The slash separates the numerator (number above a fraction line) and denominator (number below).Mixed numerals (mixed fractions or combined numbers) create as creature separated through one space and fraction i.e., 12/3 (having the very same sign). An instance of a an adverse mixed fraction: -5 1/2.Because slash is both indications for portion line and division, we recommended use colon (:) together the operator of division fractions i.e., 1/2 : 3.Decimals (decimal numbers) get in with a decimal suggest . and they are immediately converted to fractions - i.e. 1.45.The colon : and also slash / is the price of division. Deserve to be offered to divide combined numbers 12/3 : 43/8 or deserve to be supplied for write facility fractions i.e. 1/2 : 1/3.An asterisk * or × is the symbol for multiplication.Plus + is addition, minus authorize - is subtraction and also ()<> is mathematical parentheses.The exponentiation/power symbol is ^ - because that 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• spring exponents: 16 ^ 1/2• adding fractions and 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• portion to Percent: 1/8 %• comparing fractions: 1/4 2/3• multiplying a portion by a whole number: 6 * 3/4• square source of a fraction: sqrt(1/16)• reducing or simple the fraction (simplification) - separating the numerator and denominator the a portion by the same non-zero number - equivalent fraction: 4/22• expression v brackets: 1/3 * (1/2 - 3 3/8)• compound fraction: 3/4 that 5/7• fountain multiple: 2/3 of 3/5• division to find the quotient: 3/5 ÷ 2/3The calculator follows renowned rules for order the operations. The most usual mnemonics for remembering this order of work are: PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction BODMAS - Brackets, of or Order, Division, Multiplication, Addition, Subtraction.

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