a)Add: 1 /5 + 1 /10 = 1 · 2 /5 · 2 + 1 /10 = 2 /10 + 1 /10 = 2 + 1 /10 = 3 /10
The common denominator you can calculate as the least common multiple of the both denominators - LCM(5, 10) = 10
Add: 3 /10 + 3 /10 = 3 + 3 /10 = 6 /10 = 3 /5
The common denominator you can calculate as the least common multiple of the both denominators - LCM(10, 10) = 10
c)Add: 1
21
+ 9
56
= 1 · 8
21 · 8
+ 9 · 3
56 · 3
= 8
168
+ 27
168
= 8 + 27
168
= 35
168
= 5
