To determine the number of whole extra-large pizzas needed for a picnic with 26 people, let's break down the problem step by step.
1. Understand the Serving Capacity: One extra-large pizza serves about 4 people.
2. Total Number of People: There are 26 people attending the picnic.
3. Calculate the Number of Pizzas Needed:
- Each pizza serves 4 people.
- To find out the total number of pizzas required, we need to divide the total number of people by the number of people one pizza serves. This gives us [tex]\( \frac{26}{4} \)[/tex].
4. Perform the Division:
- [tex]\( \frac{26}{4} \)[/tex] equals 6.5.
5. Determine the Number of Whole Pizzas:
- Since you can't order half a pizza and you want to ensure there's enough pizza for all the people, you will have to round up 6.5 to the next whole number.
- The smallest whole number greater than 6.5 is 7.
Therefore, you should get 7 whole pizzas for the picnic to make sure there is enough pizza for all 26 people.
