Answer:
13 nickels
Step-by-step explanation:
Let n represent the number of nickels Bob has. Then 18-n is the number of dimes, and the total value (in cents) is ...
5n +10(18-n) = 115
-5n +180 = 115 . . . simplify
65 = 5n . . . . . add 5n-115
13 = n . . . . . . . divide by 5
Bob has 13 nickels.

Answer:
The Ratios are Proportional
Step-by-step explanation:
Let,
R1 = 48 / 72 ----- (1)
R2 = 6/9 ------ (2)
If we divide right hand side of above equation by 8, we get,

Therefore, it means that, in simplified form, both ratios are same and hence proportional.
R1 : R2 = 6/9 : 6/9
