Question

You have for bookshelves, each 2 1/3 feet wide. How many feet of wall space will all 4 take up if they are placed into end?

Answer 1

Answer: 9 1/3

Step-by-step explanation: There are four of them and, assuming there is no space in between them, they all take up the same amount of space. So that means, if they were added up, it’d be 2 1/3 +2 1/3 + 2 1/3 +2 1/3. That can be simplified to 4 x (2 + 1/3). When multiplied, it equals 8 + 4/3=8 + 1 +1/3=9 + 1/3=9 1/3.

Answer 2

Step-by-step explanation:

2 1/3 × 4

1. Convert the fraction into an improper fraction

2 × 3 = 6 (2 times the denominator)

6 + 1 = 7 (the result plus the numerator)

So 2 1/3 = 7/3

2. Make 4 be divided by 1 so you can multiply across

7/3 × 4/1

3. Multiply across

(7×4)/(3×1)

4. Simplify

28/3

5. (Optional) Convert to a proper fraction

3 goes into 28 9 times with a remainder of 1 so it's 9 1/3
