A shed is planning for a large banquet thinks that 2 out of every 5 dinner guests will order he expects 800 guests at the banquet use a equivalent ratios to estimate how much soup he should prepare

He should prepare soup for 320 guests.

Step-by-step explanation:

Given:

A shed is planning for a large banquet thinks that 2 out of every 5 dinner guests will order he expects 800 guests at the banquet.

Now, to find the number of guests out of 800 to order soup.

Let the number of guests at the banquet he should prepare soup be

Guests expected at the banquet = 800.

2 out of every 5 dinner guests will order.

So, 2 is equivalent to 5.

Thus, is equivalent to 800.

Now, to use cross multiplication method to get the number of guests:

By cross multiplying we get:

Dividing both sides by 5 we get:

Therefore, he should prepare soup for 320 guests.
