Answer:
see explanation
Step-by-step explanation:
The bar above the 3 indicates the 3 is being repeated, that is
0.13333....
We require to make 2 equations with the repeating 3 after the decimal point.
let x = 0.13333... , then multiply both sides by 10 then 100
10x = 1.3333 ← equation with repeating 3 after the decimal point
100x = 13.3333 ← second equation with repeated 3 after the decimal point
Subtracting the equations eliminates the repeated 3, that is
100x - 10x = 13.333 - 1.333
90x = 12 ( divide both sides by 90 )
x = 
← divide numerator/denominator by 6, hence
0.1333... =

Answer:
Hi! You just have to take his salary as a unity (one) and substract the fractions you are given. For example; lets say you have a cake (one) and then you eat 1/8 of it. You would be left with 
of the original cake.

The answer is (d)
Answer:
-- Perfect square trinomial
---Binomial squared
Step-by-step explanation:
Given
Solving (a): Perfect square trinomial
We have:
Express as an equation
Start----------------------------
Take coefficient of n i.e. (2/3)
Half it: i.e. (1/3)
Square it: (1/63^2
Add to both sides of the equation
---------------------------End
So, we have:
Remove brackets
Solving (b): Binomial Squared
Expand
Factorize:
Factor out n + 1/3
Express as square
