Soo we just need to make these into fractions

       1                              x
           
 15,000                   300,000
all we need to do is figure out what we multiplied by 15,000 to get 300,000 all we have to do is divide 300,000 by 15,000. here is the math:)
300,000/15,000 = 20
so we got 20!!
just multiply that by the 1 in the first fraction to get x in the second fraction:)
your B 20
