A) 3/4 – 1/3     =
    9/12 – 4/12 = 5/12

b) 9/10 – 4/5    =
    9/10 – 8/10  = 1/10

c) 41/6 – 35/8        =
    164/24 – 105/24 = 59/24

A. frac{3}{4} - frac{1}{3} = frac{9-4}{12} = frac{5}{12}
b. frac{9}{10} - frac{4}{5} = frac{9-8}{10} = frac{1}{10}
c. frac{7}{9} - frac{5}{12} = frac{84-45}{108} = frac{39}{108}
d. frac{30}{6} - frac{12}{8} = 5 - frac{3}{2} = frac{10-15}{10} = - frac{5}{10}
