16. Ben drew plans for a new garage. On the

plans, the garage is 6.4 inches long. If the

actual garage will be 18 feet long, what was

the scale used to create the drawing?

32 inches: 90 feet

Step-by-step explanation:

The question is asking for a ratio of inches to feet. Since you want the scale to be an integer, we find the lowest number to multiply 6.4 inches by to get an integer. Since 6.4 inches = 32/5, multiply by 5, leaving 32 inches. However, since you multiplied 6.4 by 5, you have to multiply 18 by 5. 6.4*5 inches: 18*5 feet, or 32 inches: 90 feet.
