Answer:
a: 11/105
Step-by-step explanation:
Simplify the following:
12/35 - 5/21
Put 12/35 - 5/21 over the common denominator 105. 12/35 - 5/21 = (3×12)/105 + (5 (-5))/105:
(3×12)/105 + (5 (-5))/105
3×12 = 36:
36/105 + (5 (-5))/105
5 (-5) = -25:
36/105 + (-25)/105
36/105 - 25/105 = (36 - 25)/105:
(36 - 25)/105
