=> 400 x .20
=> 80
=> 400 + 80
=> 480 => the total number of people who took the survey

1. To do this, you want to divide 1560 by 24.  This gives you 65.  The bottle fills 65 bottles per hour.
2. To do this divide 4290 by 78.  The result is 55.  It would take the groundskeeper 55 hours to drain the pond.
3. They are similar because you break up pieces of the number and then you combine them.

### The area of a mirror is 225 square inches, and its width is 13 3/4 inches. Will the mirror fit in a space that is 15 inches by 16 inches? Explain

If you multiply length times width to get area, it's the same with division. You do area divided by length or width. The equation would be 225 divided by 13 3/4. 225/13 3/4= 16.36 inches. 16.36 > 16 inches, so the answer would be no. (The mirrors length and width are 13 3/4 inches by 16 9/25)

### A 91 square foot bathroom has a length of 13 feet. what is the width of the bathroom

The answer is 7 ft. The bathroom has rectangular shape. The area (A) of a rectangle is the product of the width (w) and length (l): A = w * h. The bathroom is rectangular. We know that A = 91 ft^2 and l = 13 ft. Let's substitute them in the formula for the area: 91 ft^2 = w * 13 ft. w = 91 ft^2 : 13 ft. w = 7 ft. The width of the bathroom is 7 ft.Hope this helps.
