Answer:

x=7.2

Explanation:

Cross multiply

4/5=x/9

5*x=4*9

5x=36

Divide by 5 on both dies

x=7.2

OR

Multiply both sides by 9

4/5=x/9

9*4/5=x/9*9

7.2=x

Hope this helps! :)

Answer: x = 7.2

Explanation:

First, we need to isolate the x variable in order to solve for this. In order to do this, we need to multiply 9 on both sides. This is because we are dividing x by 9. So by doing this, the equation is now (4/5)9 = x. Now we need to solve what 4/5 times 9 is. If we do 4*9 , we now have 36/5. 36/5 is 7.2. We can also first do 4 divided by 9 which is 0.8, then multiply that by nine. Either way, the answer is x = 7.2.

Hope this helps!
