the ratio of the length of a rectangle to its width is 6:5. its length is 24 in. what is its width
Six is to 24 in as 5 is to its width
6/24 = 5/x
x = 5 x 24/6 = 20 inches = width
We know that the ratio is 6:5, therefore, we also know that 24/6 is 4. to undo that equation, we multiply it by four, getting 24. Then we can do the same to both sides, changing 6:5 to 24:20, and your answer, 20.
