Answer:
14 1/2
Step-by-step explanation:
Ok let's get started!
First things first...
Let's see what information we have!
Monday practice: 2 1/2 hours
Tuesday practice: 1 3/4 hours
Wednesday practice: 3 hours
First Step:
We need to put each fraction in improper form, so now it will look like this:
Monday practice: 5 / 2 hours
Tuesday practice: 7 / 4 hours
Wednesday practice: 12 / 4 hours
Now why did I put the Wednesday practice in terms of 4? Because we need to find a common denominator and that will be 4 so I made life easier and did it ahead of time!
Second Step:
We now need to put the Monday practice hours with a denominator of 4.
So we need to multiply the denominator by 4 and will do the same for the numerator so now we get:
5*2 / 2*2
Which is 10 / 4!
(hour)
Third Step:
Now we need to add a weeks worth of practice!
10 / 4 + 7 / 4 + 12 / 4 = 29 / 4
So, in a week Cory practices 29 / 4 hours, that's a lot!
Fourth Step:
Now we must find how much she does in 2 weeks. To do so we will do something a little more different then usual. We are going to put 29 / 4 in mixed number form. We will get 7 1/4.
Fifth Step:
Last step!
We will multiply 7 and 1/4 by 2,
7*2 and 1 / 4*2 =
14 and 2 / 4
Now we can still simplify 2 / 4 down to 1 / 2.
So our answer is.....
14 1/2
Sixth Step:
I lied there is one more step.....
REJOICE!!!!
We got through the math problem WHOOP! WHOOP!
