To solve 30, you need to square root 200. 200 square root would be 14.14 but rounded to the nearest foot would be 14 feet.
To solve 31, you would need to divide the numerator by the denominator. 1 / 16 would be 0.0625. This means it is a terminating decimal since it doesn't keep going on and on and on. A repeating decimal is 1 / 3. It would be 0.3333333333333 and so forth. To show a repeating decimal, put a little line over the decimal value that is repeating. In this example, it would be the 3 in 0.3.
To solve 32, you need to use square root again. The square root of 500 is 22.36. Rounding to the nearest tenth of an inch would make it 22.3 inches.
To solve 33, you would need to solve the amount of photos and then combine their area together. There are 60 shelves with 60 photos each. 60 x 60 = 360. Each photo is 4 inches squared. 360 x 4 = 1440 inches.
