To find the ratio of sandwiches to chicken wings, we can write it as:
Number of sandwiches : Number of chicken wings = 40 : 25
So the ratio of sandwiches to chicken wings is 40:25.
You can also simplify this ratio by dividing both numbers by 5:
40 ÷ 5 = 8
25 ÷ 5 = 5
Thus, the simplified ratio is 8:5, but the original ratio (40:25) is also a correct answer.
