The answer is:[C]: " ⁷/₆ " . ____________________________________ Note: ____________________________________ (5/3) - (1/2) = ? ; ____________________________________ The LCD (lowest common denominator) of "2 and 3" is "6" ;
So we need to rewrite EACH fraction in the problem as a fraction with "6" in the denominator ; ____________________________ (5/3) = (?/6) ? ; (6÷3=2) ; (5/3) = (5*2)/(3*2) = 10/6 ; ____________________________ (1/2) = (?/6) ? ; (6÷2=3) ; (1/2) = (1*3)/(2*3) = 3/6 ; ____________________________ Rewrite the problem: " (5/3) - (1/2) " ; as: ____________________________ 10/6 - 3/6 ; ____________________________________________ 10/6 - 3/6 = (10 - 3) / 6 = (7/6) = 1 ⅙ . ____________________________________________ The answer is: " ⁷/₆ " ; or, write as: " 1 ⅙" ; which corresponds to: ______________________________________________________ Answer choice:[C]: " ⁷/₆ " . ____________________________________________
