Step-by-step explanation:
The student has provided a scenario in which there is a specific ratio of onions to pickles on a burger. To find the ratio of pickles to onions, we use the information given: For every 6 onions, there are 5 pickles. The ratio is simply the comparison of the quantity of one item to the quantity of another, represented as a fraction or two numbers separated by a colon.
To write the ratio of pickles to onions, we take the number of pickles and place it first, followed by the number of onions, since the question is asking for the ratio in this specific order. Therefore, given there are 5 pickles for every 6 onions, the ratio of pickles to onions is 5:6.
