Two squares overlap. The area of the overlapped region is 1/4 of the small square's area and is 2/9 of the large square's area. What is the ratio of the area of the small square to the large square?

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

For range i think it’s area
