The equation looks like this right now: 4/5x=2/5. In order to solve for x, you need to divide both sides by 4/5. When dividing fractions, you need to remember the rule KCF (keep, change, flip) So, you will keep the first fraction, change the division sign to a multiplication sign, and flip the last fraction. Now you have 2/5*5/4. When you do that, you get 10/20. Simplify it, and you end up with 1/2, and that is your answer. I hope that helped! :)
