You are watching: 7/8 plus 7/8
1 3/4 + 7/8 = 21/8 = 2 5/8 = 2.625Spelled cause words is twenty-one eighths (or two and also 5 eighths).
Convariation a mixed number 1 3/4 to a imcorrect fraction: 1 3/4 = 1 3/4 = 1 · 4 + 3/4 = 4 + 3/4 = 7/4To uncover a brand-new numerator:a) Multiply the entirety number 1 by the denominator 4. Whole number 1 equally 1 * 4/4 = 4/4b) Add the answer from previous step 4 to the numerator 3. New numerator is 4 + 3 = 7c) Write a previous answer (new numerator 7) over the denominator 4.One and also three quarters is seven quarters
Rules for expressions with fractions: Fractions - usage the slash “/” in between the numerator and denominator, i.e., for five-hundredths, enter 5/100. If you are making use of combined numbers, be certain to leave a single room between the totality and also fractivity component.The slash separates the numerator (number over a fraction line) and also denominator (number below).Mixed numerals (mixed fractions or blended numbers) write as non-zero integer separated by one room and also fractivity i.e., 12/3 (having actually the very same sign). An instance of an unfavorable blended fraction: -5 1/2.Due to the fact that slash is both indications for fraction line and also department, we recommfinished usage colon (:) as the operator of department fractions i.e., 1/2 : 3.Decimals (decimal numbers) enter through a decimal point . and they are instantly converted to fractions - i.e. 1.45.The colon : and slash / is the symbol of division. Can be supplied to divide mixed numbers 12/3 : 43/8 or can be provided for compose complex fractions i.e. 1/2 : 1/3.An asterisk * or × is the symbol for multiplication.Plus + is enhancement, minus sign - is subtractivity and also ()<> is mathematical parentheses.The exponentiation/power symbol is ^ - for example: (7/8-4/5)^2 = (7/8-4/5)2
Examples: • adding fractions: 2/4 + 3/4• subtracting fractions: 2/3 - 1/2• multiplying fractions: 7/8 * 3/9• dividing Fractions: 1/2 : 3/4• exponentiation of fraction: 3/5^3• fractional exponents: 16 ^ 1/2• adding fractions and also combined 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• Fraction to Decimal: 1/4• Fractivity to Percent: 1/8 %• comparing 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 simplifying the fraction (simplification) - dividing the numerator and also denominator of a fraction by the very same non-zero number - equivalent fraction: 4/22• expression with brackets: 1/3 * (1/2 - 3 3/8)• compound fraction: 3/4 of 5/7• fractions multiple: 2/3 of 3/5• divide to uncover the quotient: 3/5 ÷ 2/3The calculator follows famous rules for order of operations. The many widespread mnemonics for remembering this order 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, Subtractivity.

GEMDAS - Grouping Symbols - brackets (), Exponents, Multiplication, Division, Addition, Subtractivity. Be cautious, always execute multiplication and division before enhancement and also subtraction. Some operators (+ and also -) and (* and /) has actually the same priority and also then must evaluate from left to ideal.
