To simplify a ratio, you need to find the greatest common divisor (GCD) of the two numbers and then divide both numbers by the GCD.

For the given ratio 45:15, find the GCD of 45 and 15. The factors of 45 are: 1, 3, 5, 9, 15, 45. The factors of 15 are: 1, 3, 5, 15. The GCD of 45 and 15 is 15.

Now, divide both numbers by the GCD to simplify the ratio:

45 ÷ 15 = 3
15 ÷ 15 = 1

So, the simplified ratio is 3:1.

Therefore, the correct answer is B. 3:1

45:15 = (3*15):(1*15) = 3:1
