Final answer:
Crystal can fill 20 pots with 5 bags of soil.
Step-by-step explanation:
To find out how many pots Crystal can fill with 5 bags of soil, we need to divide the total number of bags by the amount of soil needed for each pot. Crystal estimates that she will need 1/4 of a bag of soil for each pot. So, we can set up a proportion:
1/4 bag / 1 pot = 5 bags / x pots,
where x is the number of pots Crystal can fill. To solve this proportion, we can cross-multiply and then divide:
1/4 * x = 5 * 1,
x/4 = 5,
x = 20.
Therefore, Crystal can fill 20 pots with 5 bags of soil.
