Find the LCM between the denominators.
The LCM is 36
Divide he LCM for the denominators, then multiply the result for the numerator.

You get 25/36 and you can't simplify it
That graph seems to be complementary since both angles sum up to be 180 degrees.
The following gives 28 in multiplication tables (for positive integers):
1x28
2x14
4x7
7x4
14x2
Of course you can go into -28x-1 etc. but I feel this is adequate. If you'd like more just say.
You need the revenue of year 2 to calculate what percent you have to increase it to reach 3 million in year 3.
Let R2 be the revenue of year 2 and R3 the revenue of year 3.
The formula of percent increase is:
% increase = ( R3 - R2 ) / R2 *100
=> % increase = (R3 / R2 - 1) * 100
So, given R3 is 3 million
=> % increase = (3,000,000 / R2 - 1) * 100
So, you just have to replace R2 to get the solution.
Let's do one example:
R2 = 2 million
=> % increase = (3,000,000 / 2,000,000 - 1) * 100 = (0.5) * 100 = 50
So, if the revenue of year 2 was 2 million, he needs to increase it 50% to reach 3 million.
Y = 5/x
If you want to shift the function 4 units left, you can add 4 to the x-value in the parent function:
y = 5 / ( x + 4 )
After that, you can add 3 to your function to shift it up 3 units.
y = 5 /( x + 4 ) + 3 ( the final equation )
