To be able to find the value of X, we have to cross multiply the two fractions then solve the equation. As so,
6/4 = 15/x
Cross Multiply:
6 x X = 6x 4 x 15 = 60
We cross multiplied, now we can set up the equation:
6x = 60
Simplify: (Get X by itself)
Divide 6 on each side
6 / 6x = 60 / 6 x = 60 / 6 x = 10
Now we have the total of X! To check our answer, we can substitute X for 10 in the original equation. As so:
6/4 = 15/10
6/4 = 1.5 15/10 = 1.5
Correct! Our answer is X = 10!
