Ryan is painting a large butterfly mural on a wall it takes him 2 hours to paint 1/5 of the wall how long will it take him to complete the mural

If it takes Ryan 2 hours to paint 1/5 of the wall, it means it will take him 2*5 = <<2*5=10>>10 hours to complete the mural. Answer: \boxed{10}.

To calculate how long it will take Ryan to complete the mural, we need to determine how many times he needs to paint 1/5 of the wall to cover the entire wall.

Since it takes Ryan 2 hours to paint 1/5 of the wall, we can calculate the number of times he needs to paint 1/5 to cover the whole wall:

1 wall / (1/5 wall per 2 hours) = 5 walls / 1 wall per 2 hours = 5/1 * 2 hours = 10 hours

Therefore, it will take Ryan 10 hours to complete the mural.

To find out how long it will take Ryan to complete the mural, we can use proportions. We know that it takes him 2 hours to paint 1/5 of the wall. Let's set up the proportion:

2 hours / 1/5 of the wall = x hours / the entire wall

To solve for x, we can cross multiply:

2 hours * the entire wall = x hours * 1/5 of the wall

2 hours * the entire wall = x hours * 1/5

Now, divide both sides of the equation by 1/5 to isolate x:

(2 hours * the entire wall) / (1/5) = x hours

Simplify:

(2 hours * the entire wall) * (5/1) = x hours

10 hours * the entire wall = x hours

So, it will take him 10 hours to complete the mural.
