Step-by-step explanation:
Percentages and ratio:
The double of a measure, for example, is 200% of the measure.
So 1000% of a measure is 10 times the measure.
There are 90 million pet dogs in the US. The number of dogs is 1000% the number of reptiles.

OK, this written in numbers is
But, fractions can not divide. So we need to multiply one by the reciprocal of the other. The reciprocal of a fraction is itself flipped upside down. For example, the reciprocal of 1/2 would be 2/1.
So, we will multiply 3/2 by 4/1. We know how to do this, it is simply 3/2*4=12/2=6.
So, the answer is n = 6. That would be answer c, because 6 is between 5 and 7.
