it takes 5 hr for 8 cooks to prepare the food for a wedding rehersal dinner how long will it take 9 cooks?

8/9 as long as before.

What is 8/9 of 5 hours?

To find out how long it will take for 9 cooks to prepare the food for the wedding rehearsal dinner, we can use a simple proportion.

First, we need to establish a relationship between the number of cooks and the time it takes to prepare the food. From the given information, we know that it takes 5 hours for 8 cooks.

Let "x" be the unknown time it takes for 9 cooks. We can set up the proportion:

8 cooks / 5 hours = 9 cooks / x

To solve this proportion, we can use cross-multiplication:

8 * x = 5 * 9

Simplifying further:

8x = 45

Now, divide both sides of the equation by 8 to isolate "x":

x = 45 / 8

Calculating this division:

x ≈ 5.625

Therefore, it will take approximately 5.625 hours for 9 cooks to prepare the food for the wedding rehearsal dinner.
