You are watching: 1/4 of 1/2 of 1/5 of 200
2 1/2 = 2 1/2 = 2 · 2 + 1/2 = 4 + 1/2 = 5/2 = 2 1/2 = 2.5Spelled result in words is five halfs (or two and also one half).
switch a combined number 2 1/2 to a improper fraction: 2 1/2 = 2 1/2 = 2 · 2 + 1/2 = 4 + 1/2 = 5/2To find new numerator:a) multiply the totality number 2 by the denominator 2. Whole number 2 same 2 * 2/2 = 4/2b) include the answer from previous step 4 to the numerator 1. Brand-new numerator is 4 + 1 = 5c) create a previous answer (new numerator 5) end the denominator 2.Two and one half is 5 halfs
Rules for expressions with fractions: Fractions - usage the slash “/” in between the numerator and also denominator, i.e., because that five-hundredths, get in 5/100. If you room using mixed numbers, be sure to leaving a solitary space between the entirety and fraction part.The slash separates the molecule (number above a portion line) and denominator (number below).Mixed numerals (mixed fractions or blended numbers) create as non-zero creature separated by one space and portion i.e., 12/3 (having the same sign). An example of a an adverse mixed fraction: -5 1/2.Because cut is both signs for fraction line and division, us recommended use colon (:) together the operator of department fractions i.e., 1/2 : 3.Decimals (decimal numbers) get in with a decimal point . and they are instantly converted to fountain - i.e. 1.45.The colon : and slash / is the symbol of division. Can be supplied to divide combined numbers 12/3 : 43/8 or can be used 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 mathematics parentheses.The exponentiation/power price is ^ - for example: (7/8-4/5)^2 = (7/8-4/5)2
Examples: • including fractions: 2/4 + 3/4• subtracting fractions: 2/3 - 1/2• multiplying fractions: 7/8 * 3/9• dividing 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 also fraction: 5 ÷ 1/2• complicated fractions: 5/8 : 2 2/3• decimal to fraction: 0.625• portion to Decimal: 1/4• fraction to Percent: 1/8 %• to compare fractions: 1/4 2/3• multiplying a portion by a whole number: 6 * 3/4• square root of a fraction: sqrt(1/16)• to reduce or simple the fraction (simplification) - separating the numerator and also denominator the a fraction by the very same non-zero number - tantamount fraction: 4/22• expression with brackets: 1/3 * (1/2 - 3 3/8)• link fraction: 3/4 that 5/7• fountain multiple: 2/3 of 3/5• division to uncover the quotient: 3/5 ÷ 2/3The calculator follows well-known rules because that order that operations. The most typical mnemonics because that remembering this stimulate 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.
