Elliott's bed is 75 inches long. during his growth spurt, elliott grew 6 inches. before his growth spurt, he was 5 feet 11 inches tall. how much shorter is elliott's bed than elliott?

Firstly, you need to convert 75 inches into feet and inches. 75 inches in feet and inches is 6ft 3 inches.
Elliot was 5ft 11 then grew 5 inches.
There is 12 inches in a foot, meaning he will become 6ft 4. 
You've then got to subtract 6ft 3 from 6ft 4, and this leaves you with 1 inch.
Therefore, Elliott's bed is 1 inch shorter than him.
Hope this helps :) 

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.
