Ineed the equation and the answer! !

So 3/4 of the total students, s, is 1464 students voted. 
3/4 * s = 1464
divide both sides by 3/4
s = 1464 / 3/4
Remember since it is too complicated to divide by a fraction you can do Keep, Change, Flip
That is you keep to first number, change the division sign to multiplication and flip the fraction
s = 1464 * 4/3 
s = 1952

to check:
3/4 * 1952 
that is 1464

There is a total of 1952 students of which 1464 voted. 

Hope this helps :)

The graph isn’t that clear

The answer is 16.64 feetyour welcome
