It's easier then you'd expect it to be. There's no need to convert the fractions so that they all have a common denominator like you'd have to do when adding or subtracting fractions.
Let's take a look at something really simple.
We can multiply the numerators together so 1*2. We can multiply 4*6 to get the denominator.
This means that our fraction becomes 
.
Now I'm assuming since you already know how to add fractions you'll know how to simply fractions. So 2/24 will become 1/12.

Answer:
The answer is D - 382
Step-by-step explanation:
The volume of a sphere can be calculated using this simple formula:
V = 4/3 x 3.14(pi) x r cubed(to the third)
So, V = 4/3 x 3.14 x 4.5 cubed
V = approximately 382
Answer:
angle a is 116 degrees
Step-by-step explanation:
ok so first we have to make everything equal to 180 because every triangle is 180 degrees so it would be written like this:
(14x + 4) + (5x - 1) + (2x + 9) = 180
Then, we solve for x and x equals 8
After this we plug 8 back into the angle so it would be written like this:
14(8) + 4
This equals 116 degrees.
