Joslani is making slime and the recipe calls for 5/8 teaspoon of coloring. He only has a 1/8 measuring tool available. How many times will he need to fill his measuring spoon to have enough coloring to follow the recipe?
To find how many times Joslani needs to fill his measuring spoon, we need to divide the total amount of coloring needed by the amount the spoon can hold.
5/8 / 1/8 = (5/8) * (8/1) = 40/8 = <<(5/8)/(1/8)=5>>5
Therefore, Joslani will need to fill his measuring spoon 5 times to have enough coloring to follow the recipe. Answer: \boxed{5}.
