Answer:
11
Step-by-step explanation:
Making the appropriate substitutions, we get
3/7 r + 5/8 s => 3/7 (14) + 5/8 (8).
Notice how this can reduced:
3(14) 5(8)
----------- + --------- = 6 + 5 = 11
7 8
The ratio of kittens to puppies is 3:1, as 36 is 3 times 12, therefore there are 3 kittens to one puppy.
