What is the value of x in 6 over 21 and 10 over x?
x=35How I got the answer:What is the value of x? Given the following:6/21 = 10/xFirst cross mutiply6 * x = 6x = 10 * 21so 6x = 210Then divide both sides by 6 and you'll get x=35Proof x = 35:6 / 21 = 0.285714286,10 / 35 = 0.285714286, and 0.285714286 = 0.285714286.
