Final answer:
To find the total number of lights on the strand, set up a proportion. To find the total number of Whos at the table, set up another proportion.
Step-by-step explanation:
To find the total number of lights on the strand, we can set up a proportion. Since one light represents one percent of the total lights, we can write the proportion as 1/1 = 1%/x, where x is the total number of lights. To solve for x, we can cross multiply and divide: 1*x = 1%*1. This simplifies to x = 100 lights, so there are 100 total lights on the strand.
Similarly, to find the total number of Whos at the table, we can set up another proportion. If the Grinch and his dog represent 5%, we can write 5/100 = 5%/x, where x is the total number of Whos. Solving for x gives us x = 100 Whos, so there are 100 total Whos enjoying the Christmas feast, including the Grinch and his dog.
