Answer: If he has 3 mystery books, and those are 1/8 of his whole collection, he has 24 books.
Step-by-step explanation:
3 = 1/8 × x
multiply both sides by the reciprocal of 1/8 which is 8/1 ("flipped fraction")
8 × 3 = 8/1(1/8) x <em>When you multiply a fraction by its reciprocal, it produces 1, so it "cancels" in the multiplication</em>
<em>24 = x </em>
<em>This may seem complicated, but understanding the process will help you solve more complicated questions like this in the future, I hope.</em>

The least common multiple of 5 and 8 is 40. This is because when you go by multiples of 5 and 8 the multiple that is the “smallest number” (LCM) of both numbers is 40. :)
So first we would convert 4 1/2 foot lengths into a decimal.
4.5 feet
Now we divide 25 by 4.5
25 ÷ 4.5 = 5.5
So Yancy can cut the board into five 4 1/2 foot lengths because the question says how many can he cut.
You take 300 - 99 you get 201 so you still have 201lbs so then 3 times 67 is 201 so it would be B
