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>

Hope this helps!
If Fiona is to divide the first expression by the second one, clearly only the first term of the first expression is divisible. The remaining terms of the fist expression will remain as the remainder. The remainder from the division done by Fiona should be 5x - 3.
Answer: $7787.99
Step-by-step explanation:
We know that the formula to find the periodic payment on an annuity is given by :-
, where PV is the present value , r is the rate of interest ( in decimal ) and n is the number of payments.
Given : Present value : $36000
Rate of interest = 8%=0.08
Time period = 6 years
Then , the periodic payment will be :-

Hence, the payment size is $7787.99.
