Explanation:

You can solve it with an equation like this:
\frac{x}{6}=\frac{40}{8}x6=408

\frac{x}{6}=5x6=5

x=6*5x=65

x=30x=30

Note: Assuming you are looking for the value of "Blank"

Explanation:

We can rewrite this problem as:

"Blank"/6 = 40/8Blank6=408

Now, we can multiply each side of the equation by color(red)(6)6 to solve for "Blank"Blank while keeping the equation balanced:

color(red)(6) xx "Blank"/6 = color(red)(6) xx 40/86×Blank6=6×408

cancel(color(red)(6)) xx "Blank"/color(red)(cancel(color(black)(6))) = 240/8

"Blank" = (30 xx 8)/8

"Blank" = (30 xx color(red)(cancel(color(black)(8))))/color(red)(cancel(color(black)(8)))

"Blank" = 30/1

"Blank" = 30

30

Explanation:

x÷6 =40÷8

x/6 =40/8

Multiply both sides by 6

x/cancel6*cancel6 =40/8*6

x=40/(cancel2*4)*(cancel2*3)=40/4*3=10*3=30

x÷6 =40÷8=>x=30
