Answer:
30
Step-by-step explanation:
2700/90 = 30
27/9 = 3
100/10 = 10
3*10 = 30
a) because the denominators are the same add the numerators:
1 1/5 + 3 2/5 = 4 3/5
b) rewrite the fractions to have a common denominator:
1/2 = 3/6
1/3 = 2/6
Now subtract:
4 3/6 - 1 2/6 = 3 1/6
Answer: 6.48

MAD formular is addition of variance point /population size
n∑∣xi−xˉ∣
If it increases at 3.9% a month, then in a year it increases 46.8%.
This is because a year has 12 months and so take 3.9(12)=46.8
I would have to say 32,4 but i would double check it
