I'm going to do this two ways, one using a calculator and one not.
Let the total amount of his estate be x.
Equation and Solution
If you have a calculator with an a b/c key on it you can do this problem easily, or at least the fractional part will be easy.
First: develop the equation
(4/17) x + (7/13)x + 2/3 x + 2 000 000
Solve the equation
Use the a b/c key on your calculator if you have one. If not go down the second solution part. Put a fraction in as follows.
4 a b/c 17 + 7 a b/c 13 + 2 a b/c 3 =
You should get 1 r 16 r 51
What this translates into is 1 292 / 663 of x
or 955/663 x + 2000000
So the total of fhis estate is
(955/663) x + 2000000 <<<< answer In decimal form you get
1,44 x + 2000000 <<<< answer in decimal.
Note: you cannot solve this to the exact amount of his estate because the fractional amount exceeds x which assumed to be the total amount of his estate.
By hand
Find the ;lowest common denominator of 13 17 and 3. Since all of them are prime numbers the lowest common denominator is 13 * 17 * 3 = 663
\
Next set up the 3 fracttions so the denominator = 663
4 / 17 =( 4 * 13 * 3) / 663 = 156 / 663
7/13 = 7 * 17*3 / 663 = 357 / 663
2/3 = 2*13 * 17 / 663 = 442 / 663
Now add these up 156/663 + 357/663 + 442/663 = 955 / 663 This is irreducible
This fraction is over 1 so it cannot represent the total amount in his estate. It is too large.
(955/663)x + 2000000 <<<<<< fractional answer
1.44x + 2000000 < decimal answer.
You can solve it like this
2=milk (a); 1=milk (b)
9=tea (a); x= tea (b)
2:9=1:x (then multiply means and the extremes)
(means are 9 and 1; extremes are 2 and x)
9=2x
9/2= x
4.5 or 4 1/2=x
Therefore, using 1 litre of milk, we can have 4 1/2 tea.

The series is neither arithmetic or geometric.
The pattern is
1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
n^2 is the pattern where n is the position in the series.

Answer: = 11.88
This is a 3 step / 4 show workings.
10.7 + Percentage increase = 11%
10.7 + (11% × 10.7) = 10.7 + 11% × 10.7
(1 + 11%) × 10.7 = (100% + 11%) × 10.7
111% × 10.7 = 111 ÷ 100 × 10.7
111 × 10.7 ÷ 100 = 1,187.7 ÷ 100
11.877 ≈ 11.88
