The final answer will be negative because a positive divided by a negative is a negative. Let's condense this into...
-(158÷135)
How many 135s are in 158? One, because two "135s" (which is 270) is greater than 158, but 135 isn't. So we know the mixed number will be 1 + (a fraction). What's the Fraction? We can find this by subtracting 135 from 158, (158 - 135) = 23. The fraction is 23/158.
The answer is, -1, 23/158.
27.5+117=144.5 cm is the answer
66%, then 2/3, and lastly 0.67. 2/3 is repeating so it is more then 66% but less than 0.67

Answer:
20,176,803
Step-by-step explanation:
This geometric series has a first term of 3 and a common ratio of 21/3 = 7. The formula for the sum of n terms of a series with first term a1 and common ratio r is ...
Sn = a1·(r^n -1)/(r -1)
For a1=3, n=9, and r=7, the sum is ...
S9 = 3·(7^9 -1)/(7 -1) = 3·40353606/6 = 20,176,803
The sum of the first 9 terms is 20,176,803.
