a. Yes, the sum of the percentages is greater than 100 percent.
Substitue w for 1/9 and you'll get 1/2 (1/9) +2. Multiply 1/2 by 1/9 and the equation will be 1/18 + 2. The answer will be 2 1/18
Answer:
1200 hope this help you! ;)
D18∈{1,2,3,6,9,18}
suma e 1+2+3+6+9+18= 39
D81∈{1,3,9,27,81}
suma e 1+3+9+27+81=121
