Kelly bought 3 peppers, 2 onions, and 4 tomatoes. what is the ratio of peppers to all the vegetables kelly bought

If there is 3 peppers, yo find the other part of the ratio just add the 2 onions and 4 tomatoes to get the ratio of 3:6

Adding up all the vegetable you have 3 peppers, 2 onions and 4 tomatoes you have 9 items( all the vegetables) but only 3 are peppers so it’s a 3:9 ratio
