You can put this solution on YOUR website! If the ratio of fast readers to slow readers is 9 to 5,
and there 4,716 fast readers, how many slow readers are
there? ( show your work )
W is to X as Y is to Z
can be written in equation form as
W/X = Y/Z
Your problem essentially says
NUMBER OF FAST READERS is to NUMBER OF SLOW READERS as
9 is to 5.
Let x = the number of slow readers, then since the number
of fast readers is given as 4716, we can say
4716 is to x as 9 is to 5
which can be written as this equation:
4716/x = 9/5
Multiply both sides by LCD = 5x, or what amounts to the
same thing, cross-multiply, and get
23580 = 9x
x = 23580/9
x = 2620
