Show (4+5/7) - (2+1/3) as a single mixed fraction.
Mixed number -> top heavy fraction: 4 + 5/7 = ((47)+5)/7 = (28+5)/7 = 33/7 2+ 1/3 = ((23)+1)/3 = (6+1)/3 = 7/3 Common denominator by multiplying by each others: 33/7 = (333)/(73) = 99/21 7/3 = (77)/(37) = 49/21 Performing the subtraction: 99/21 - 49/21 = 50/21
