Here's the data we have:

----

Atlanta Braves: 9

Chicago Cubs: 9

Colorado Rockies: 1

L.A. Dodgers: 1

New York Mets: 10

Philadelphia Phillies: 3

Pittsburg Pirates: 6

Boston Red Sox: 5

Texas Rangers: 1

----

We need to figure out what fraction of the people liked either the Philadelphia Phillies or the Pittsburg Pirates team best.

3 liked the Philadelphia Phillies, and 6 people liked the Pittsburg Pirates

3+6 = 9 people's favorites were one of these two teams

There were a total of 45 classmates. Let's write these two numbers as a fraction

$${\frac{{\mathtt{9}}}{{\mathtt{45}}}}$$

Divide the top and bottom by 9 to reduce tis fraction

$${\frac{{\mathtt{1}}}{{\mathtt{5}}}}$$

There you go, 1/5 people liked one of these two teams.

Ornstein is correct, ABC is the answer.

Right now we have:

A =1/3

B = 3/4

C =  5/6 

To figure this out let's make all of the measurements have a common deminator (same number of the bottom of the fraction)

A =1/3*4/4

A = 4/12

------

B=3/4*3/3

B = 9/12

-----

C=5/6*2/2

C = 10/12

Now we can easily compare these and see that A is the smallest, B is the next biggest, and C is the biggest!

Ok, I see what I did wrong.

I assumed pi = 3.14, but really pi just keeps going forever with decimal digits.

Because everything is multiplied together, then rounded, my answer was one off.

Thanks Melody.

To find the lateral surface area of a cylinder, we can use the formula:

height*circumference

and to find the circumference, we can use:

diameter*pi                   ---Note: this could also be 2 times radius times pi. It's saying the same thing.

So really, our equation to find the lateral surface area of a cylinder is 

height*diameter*pi

Let's plug in our numbers:

45*14*3.14

1978.2

round up to a whole number

1978 cm

I'd use this method beause it's really simple to just plug in three numbers and solve the question. :)

The equation you wrote isn't very clear...so the best I can do is interpret what you were trying to ask.

You wrote "x-4(1/3)=x 4(1/6)" there's no math symbol between the x and 4 before the second parentheses.I'm going to guess that you wanted there to be a + sign there.

x-4(1/3)=x+4(1/6)

x-4(1/3)=x+4(1/6)

x(1/3)-4(1/3)=x(1/6)+4(1/6)

1/3x-4/3 = 1/6x + 4/6

-1/6x        -1/6x                      ---Subtract 1/6x from both sides

1/6x-4/3=4/6

      +4/3  +4/3                ---Add 4/3 to both sides

1/6x = 4/6+4/3   

1/6x = 4/6+8/6         ---4/3 is the same thing as 8/6

1/6x = 12/6

1/6x = 2

*6      *6             ---multiply by 6 on both sdes

x = 12

Let's check it by putting 12 in for x:

12-4(1/3)=12+4(1/6)

8(1/3) = 16(1/6)

8/3 = 16/6

8/3 = 8/3                        ---Divide the top and bottom of the right side by 2

First we have to make all the fractions have common deminators.

$${\frac{{\mathtt{1}}}{{\mathtt{54}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{23}}}{{\mathtt{36}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{263}}}{{\mathtt{162}}}}$$

Now I'll multiply the first fraction by 6/6. I'll multiply the second fractions by 9/9, and I'll multiply the last fraction by 2/2. Now we have common denominator!

$${\frac{{\mathtt{6}}}{{\mathtt{324}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{207}}}{{\mathtt{324}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{526}}}{{\mathtt{324}}}}$$

Add them together,

$${\frac{{\mathtt{739}}}{{\mathtt{324}}}}$$

or

$${\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{91}}}{{\mathtt{324}}}}$$

or

$${\mathtt{2.280\: \!864\: \!197\: \!530\: \!864\: \!2}}$$

The equation to figure out the area of a circle is 

$${\mathtt{Jemmy}}{\mathtt{\,\small\textbf+\,}}{\mathtt{40}} = {\mathtt{40}}{\mathtt{\,\small\textbf+\,}}\underset{{\tiny{\text{Error: Unknown Identifier}}}}{{\mathtt{Jemmy}}}$$

Hmmm...this looks more like an equation for a line or something...are you sure this isn't what you meant?

If this is what you meant, here's a graph for this equation for a line:

However, you did ask to solve for x.

Here's how you would do that:

y = x-3/5

+3/5   +3/5        ---Add 3/5 to both sides

y+3/5 = x

x = y+3/5
