First slot, 11 options
2nd is 10 (1 less than 1st slot)
3rd is 9
4th is 8
11*10*9*8=7920 different pizzas (assuming you can't order all 1 topping)
6 is the anwser to ur question
Answer:
3:1
You can easily figure out that 60 is a factor of 180 bc 6 is a factor of 18.
So you can simplify it to 18:6
Then divide both sides by 6 and you will get 3:1
Hope this helps ;)
