Answer:
1, 4, 20, 1
Explanation:
p is 1/3, while m is 2.
These are variables assigned to a number. When solving, we have to substitute these numbers in for the assigned variables.
5. 3p
Since p is 1/3, let's plug in 1/3 into the equation.
3(1/3)
3 times 1/3 of a cookie is just one. So the answer is 1
6. 12p
p is known as 1/3 again, so let's plug it in to the equation.
12(1/3), or better written as
To multiply fractions, we just go multiply the numerators and denominators and make it divided by each other.
We get
, so the answer is 4
7. 12m-4
We know that m is 2, so let's plug that in.
12(2)-4
Knowing PEMDAS, the order of which we solve equations (parenthesis, exponent, multiplication, division, addition, and subtraction), let's solve 12 times 2 first.
24-4=20, the answer is 20
8.9p^2
We know once again p is equal to 1/3, so let's plug it in.
The power of 1/3 to the second power is just 1/3 times 1/3, which is 1/9.
9(1/9)= if we have 9 pieces of cookies divided in 1/9ths, we will have one cookie. So the answer is 1
