To add fractions, find the LCD - lowest common denominater, and then Combine. answer is 8/9. Decimal form = 0.888888..........
For LCD find where both bottom numbers equal the same so in this case you would have to multiply 3 times 3 to equal 9. Once you do that the 2 thats on top of the 3 will also have to be multiplied by 3 so it could make sense. Now you must Combine - it would be 6/9 +2/9. you only add the top numbers and leave the bottom number.(that is what its out of). Thus the answer is 8/9.

Answer:
700 lei
Step-by-step explanation:
You have a geometric sequence for which you know the common ratio and the last term.
There are only three terms, so you can solve the problem in either of two ways.
1. The brute force method
(easiest for only a few terms)
Each term is half the one before it, so each term is double the one after it.
3rd term = 100 lei
2nd term = 200
1st term = 400
Total = 700 lei
Oana spent 700 lei
2. Using formulas (best for longer sequences)
The general formula for your sequence is
aₙ = a₁rⁿ⁻¹
For your sequence,
a₃ = 100; r = 0.5
(a) Calculate a₁
Set the last term equal to the general formula.
a₃ = a₁(0.5)ⁿ⁻¹
100 = a₁(0.5)² = 0.25a₁
a₁ = 100/0.25 = 400
(b) Calculate the sum
The general formula for the sum of a geometric sequence is

Oana spent 700 lei.
The maximum number of real roots is 5 because the degree is 5. The fundamental theorem of algebra states that the degree of a polynomial is the number of real solutions. (The degree is the highest exponent of the polynomial)
Answer:
The greater value of the given set is 98.43.
Explanation:
Here the units of the distance given for all the data is miles(mi).
So, the greater value is that value which has higher magnitude.
Values are 79.47,54.28,65.5 and 98.43
Values in their increasing order is given by
54.28 < 65.5 < 79.47 < 98.43
Values in their decreasing order is given by
98.43 > 79.47 > 65.5 > 54.28
So, the greater value of the given set is 98.43.
