The first one: They are telling you that 1 inch = 1 foot, and the window width is already 4 inches so since your going to convert into feet then look at the “key” and think okay if 1 inch = 1 foot then how many feet does 4 inches equal it would be 4ft The second question: It’s saying two cities are 5 3/4 inches apart and for every 1/2 inch = 3 miles so first you would take 5 3/4 and divide 1/2 you would get 11 1/2 but that’s not the answer that’s how many inches in all so you would take 11 1/2 and multiply 3 to get how many miles so the answer is 34 1/2 miles I hope this helps I tried to explain as much as I can so you won’t have trouble on this kinda stuff again:))
