You are watching: 4 * 7
4 3/9 - 2 7/9 = 14/9 = 1 5/9 ≅ 1.5555556Spelled lead to words is fourteenager ninths (or one and also 5 ninths).
Convariation a blended number 4 3/9 to a imappropriate fraction: 4 3/9 = 4 3/9 = 4 · 9 + 3/9 = 36 + 3/9 = 39/9To uncover brand-new numerator:a) Multiply the entirety number 4 by the denominator 9. Whole number 4 equally 4 * 9/9 = 36/9b) Add the answer from previous action 36 to the numerator 3. New numerator is 36 + 3 = 39c) Write a previous answer (new numerator 39) over the denominator 9.Four and also three ninths is thirty-nine ninths Conversion a blended number 2 7/9 to a imappropriate fraction: 2 7/9 = 2 7/9 = 2 · 9 + 7/9 = 18 + 7/9 = 25/9To discover brand-new numerator:a) Multiply the entirety number 2 by the denominator 9. Whole number 2 equally 2 * 9/9 = 18/9b) Add the answer from previous action 18 to the numerator 7. New numerator is 18 + 7 = 25c) Write a previous answer (new numerator 25) over the denominator 9.Two and salso ninths is twenty-5 ninths
Rules for expressions via fractions: Fractions - use the slash “/” between the numerator and denominator, i.e., for five-hundredths, enter 5/100. If you are utilizing mixed numbers, be certain to leave a solitary room between the entirety and fraction component.The slash sepaprices the numerator (number above a fraction line) and also denominator (number below).Mixed numerals (blended fractions or mixed numbers) compose as non-zero integer separated by one area and also fractivity i.e., 12/3 (having actually the exact same sign). An example of an adverse combined fraction: -5 1/2.Due to the fact that slash is both indicators for fractivity line and department, we recommfinished usage colon (:) as the operator of department fractions i.e., 1/2 : 3.Decimals (decimal numbers) enter via a decimal suggest . and also they are automatically converted to fractions - i.e. 1.45.The colon : and also slash / is the symbol of department. Can be supplied to divide blended numbers 12/3 : 43/8 or deserve to be provided for write complex fractions i.e. 1/2 : 1/3.An astethreat * or × is the symbol for multiplication.Plus + is enhancement, minus sign - is subtraction and ()<> 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• separating Fractions: 1/2 : 3/4• exponentiation of fraction: 3/5^3• fractional exponents: 16 ^ 1/2• including fractions and mixed numbers: 8/5 + 6 2/7• dividing integer and also fraction: 5 ÷ 1/2• complicated fractions: 5/8 : 2 2/3• decimal to fraction: 0.625• Fractivity to Decimal: 1/4• Fraction 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) - separating the numerator and also denominator of a fraction by the 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 discover the quotient: 3/5 ÷ 2/3The calculator complies with well-known 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, Subtraction.

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