If there are 170 students in 12th grade , if 75 of them want to go to one college . what is the percentage of that ?

44

Step-by-step explanation:

you have to do "part over whole equals percent over 100"

ex**

* 75 is a PART of 170

* 170 is a WHOLE because is the whole 12th grade

* you are trying to find the percentage so you would put an "x"

* you will always have the 100 at the bottom

part                 %

     =               then you start to fill in the blanks

whole            100

75                x%

    =               then you cross multiply and divide...

170             100

first multiply...

75 x 100 = 7500

then divide...

7500 / 170 = 44.1176470588

** obviously you cant have 44.1176470588 people, so you just round it to the nearest whole number and then there is your answer!!

step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
