5*21=105 and 9*21=189 it is not B because the smaller number 105 is in front of the ratio 105:189 and 5:9
Answer:
So first, they remove the denominator of x times x, because multiplication cancels out division, so then you're left with
3/1 times x = 2193

3x = 2193
To isolate 3x, you need to divide by 3.
x = 731
Hope this helped :)
