What is the probability against a spinner landing on a green section if the spinner had 15 sections and 3 of them are green?

What to do: Take the two numbers 3 and 15 and put the number of green (3) as the numerator and the number of total colors (15) as the denominator as shown here 3/15 and then you simplify it. How many time does 3 go in to 3, 1 time and how many times does 3 go in to 15, 5 times so it would be 1/5.

Fraction - 12/15

80% that it won't land on green

20%that it will land on green

(i wasn't sure what your? was, so i put both choices.)
