The ratio of the number of mystery books to the number of science fiction books is 4 : 3. the ratio of the number of science fiction books to the number of biographies is 4 : 5. if there are 48 science fiction books, find the total number of books.

220

Step-by-step explanation:

I believe the answer your looking for is:

64:48 for the first ratio.

48:60 for the second ratio.

Now we add them.

(48x) + (60x)

x = 2

(40x = 40 times 2, for example.)

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
