What’s this on a graph

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.

1. 3/6 or 1/22. 1/123. 1/84. 1/105. 2/12 or 1/6
