If m is a positive integer, and m/15 = 8.2, what is the remainder Y when m is divided by 15?

If m were a multiple of 15, the quotient m/15 would be an integer. The fact that it's a decimal tells us that 15 goes into m eight whole times and some decimal part of a time. This decimal part, 0.2 is the remainder divided by the divisor. Let Y be the remainder.
Y/15 = 0.2 = 1/5
Y = (15)*(1/5) = 3
Answer =(C)
