Well, there are 12 inches in a foot.
We have 3/12 inches (3 inches of a foot). Now, let's simplify!
What is the GCF (greatest common factor) of 12 and 3? Well, let's list out the factors (what a number divides into) of each of them.
1*12
2*6
3*4
1*3
The largest factor that we see in both of these numbers is 3, so let's divide 3/12 by 3!
3/3=1
12/3=4
So, 3 inches are 1/4 of a foot :).
You can check your answer by multiplying 12 by 1/4. Your answer will be 3!
I hope I helped! :)
First, let's find out the amount it costs to rent one movie.
175-172.25=2.75
172.25-169.50=2.75
169.50-166.75=2.75
$2.75/movie rental
-----------------------------------------------------------
A=175-2.75n
where a is the amount on the card
175 is the original amount in the card
2.75 is the cost of a movie rental times n amount of rentals
-------------------------------------------------------------------------------
n=175/2.75
=63.63
=63
n is the amount of weeks she can rent a movie
She can rent movies for 63 weeks in a row
1.) (9*2)-(9*-1)
2.)4*(9+1)
3.)A:GCF=5
B:5*(20-15)
4.) 7x+14
