Answer:
14/11
Step-by-step explanation:
Put the 3 into the one half by multiplying the 3 by the denominator. So now you have -7/2.
Then, make a common denomitator of 4, so you multiply top and bottom of fraction by 2 to get -14/4
Then, divide both sides of the equation by -11/4, and to do this, just multiply by the reciprocal of -4/11
-14/4 x -4/11 = 56/44
Simplify and get 14/11
4 laps because a mile is 1,760 yards and the 440 laps need to be divided into 1,760 so 1,760/440 is 4 so four laps are needed to complete a mile
To find the percent decrease from Saturday to Tuesday, you will find the difference between the number of customers on those days and divided by the total number of customers on Saturday.
By dividing this you will get a decimal, which then can be converted to a percent.
80-17= 63
63/80 = 0.7875
0.7875 = 78.75%
There was a 78.75% decrease from Saturday to Tuesday.
