Answer:
It takes 3.5 cups of pancake mix and 2.625 cups of water to make 21 pancakes.
Step-by-step explain
First divide each by 6 to figure out how much mix and water it takes to make one pancake
1/6 mix + .125 cups water = 1 pancake
Multiple each by 21 to know how much mix and water it takes to make 21 pancakes
3.5 mix + 2.625 water = 21 pancakes
6(x+1)=24
6x+6=24
6x=24-6
6x=18
6x/6=18/6
x=3
<span>You have to convert rates to the same units before you compare them otherwise you are not comparing like with like. For example, if you compare 3kg with 3000g you may think the second is bigger, but when converted to the same rates they are actually identical.</span>

Answer/Step-by-step explanation:
Exercise 5:
a. 180 pages was read in 5 days
Unit rate = pages per day = 180 pages ÷ 5 = 36 pages per day.
b. Number of pages of the book = 765 pages
Unit rate = 36 pages per day
Number of days to read the book = 765/36 = 21.25
It will take Kirk about 22 days to finish reading the book.
