Step-by-step explanation:
lets take a step into our imaginations, ok?
So when you divide, you're basically splitting the numerator into as many parts as the denominator.
imagine you have a chocolate bar, and it has 6 pieces and you want to split it evenly between your 3 friends.
you split it into three equal parts to get 2 pieces per person.
When you divide 0 by 0, your splitting 0 chocolate bars into 0 equal portions, which is why this problem isn't solvable.

Answer:
Carrie and Joan have 80 nickels and 40 dimes, respectively, and each one has an amount of money of 4 US dollars.
Step-by-step explanation:
Let be
and
the amounts of nickels and dimes that Carrie and Joan have, as
the total amount of money that both Carrie and Joan have. A nickel is a five cent coin and a dime is a ten cent coin.
The following equations are constructed after a careful reading on statement:
Carrie's amount of money:
(Eq. 1)
Joan's amount of money:
(Eq. 2)
Relation between amounts of coins:
(Eq. 3)
First we eliminate
by equalizing (Eq. 1) and (Eq. 2):
![0.05\cdot x = 0.10\cdot y](https://tex.z-dn.net/?f=0.05%5Ccdot%20x%20%3D%200.10%5Ccdot%20y)
Then, we reduce the resulting formula by (Eq. 3):
![0.05\cdot (y+40) = 0.10\cdot y](https://tex.z-dn.net/?f=0.05%5Ccdot%20%28y%2B40%29%20%3D%200.10%5Ccdot%20y)
![y+40 = 2\cdot y](https://tex.z-dn.net/?f=y%2B40%20%3D%202%5Ccdot%20y)
![y = 40](https://tex.z-dn.net/?f=y%20%3D%2040)
And rest of variable are now determined:
![x = 40+40](https://tex.z-dn.net/?f=x%20%3D%2040%2B40)
![x = 80](https://tex.z-dn.net/?f=x%20%3D%2080)
![c = 0.05\cdot (80)](https://tex.z-dn.net/?f=c%20%3D%200.05%5Ccdot%20%2880%29)
![c = 4](https://tex.z-dn.net/?f=c%20%20%3D%204)
Carrie and Joan have 80 nickels and 40 dimes, respectively, and each one has an amount of money of 4 US dollars.
Answer: 11.4%
Step-by-step explanation:
100% of your life is 57 years
?% will be 6.5 years?
this is a simple ratio problem:
57 --> 100%
6.5 ---> (6.5 x 100)/57 ≅ 11.4%
You have known the person for about 11.4% of your life.
