Answer:
a= 2/5
b= 30
c= 18
d= 3:2
e= No, because the fraction or ratio is the same, all you need to do is simplify it!
When you are multiplying an exponent directly into a number/variable with an exponent, you multiply the exponents together.
For example:


When you are multiplying a variable with an exponent by another variable with an exponent, you add the exponents together.
For example:



You multiply 3 into each exponent in the numerator and the denominator

When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.

When you have something like this:

You subtract the exponents together, so:

Your answer is the second option
The answer is B.
If there are 6 red marbles, 6 white marbles, and 4 blue marbles, then there are 16 marbles total. To find the probability (P) of either the red or blue marbles, you will add together the number of red and blue marbles, and divide that by the total:
(6 + 4) / (6 + 6 + 4)
10/14
This fraction can further reduce to 5/8 (by dividing both the numbers by 2).
