3x/10=24/9

3x/10=24/9           ---Multiply both sides by 10, this will "clear" the /10 on the left side

3x=24/9*10

3x = 240/9           ---Reduce the fraction on the right side

3x = 80/3      ---Divide both sides by 3 to "clear" the 3 from the left side

x = 80/3 ÷ 3           ---To divide a fraction, multiply by the reciprocal

x = 80/3 * 1/3

x = 80/9

or

x = 8.8888...

Oh, I just realized that this question has already been answered here: http://web2.0calc.com/questions/3x-10-24-9

We all three got the same answer, so it should be right!
