Question

So I have this question about an Alligator and it says k=T/B which stands for "tail length varies directly to its body length" and k=2.8/3.2 and it says it equals 7/8 and I don't understand how that is the answer.

Answer 1

2.8 as a fraction is 14/5

3.2 as a fraction is 16/5

(14/5)/(16/5)=(14/5)*(5/16)=14/16=7/8

Answer 2

k = 2.8/3.2 = 28/32 = 7/8.

 

I think it is a problem of reducing fraction.   First, multiply both the numerator and denominator by 10 to make them into whole numbers, and then devide both the numerator and denominator by their greatest common factor, which is 4 in this case.

Answer 3

2.8/3.2 = 0.875

7/8 = 0.875
