Answer:

x=10

Step-by-step explanation:

I'm assuming you needed to solve for x. Here is how you do it:

To solve 8 divided by 4/5 you do keep switch flip.

keep the first number (8), switch the sign (division to multiplication), and flip the other fraction (4/5 to 5/4) then you can just multiply across the top (8/1 *5/4) which equals 40/4. This simplified is 10
