Mr. Frank has 1.08 kilograms of fertilizer for the plants in his nursery. He wants every plant to get 93 mg of fertilizer 5 times each year. What is the number of plants he could fertilize with that amount?

1.08kg * 1000000mg/kg * 1plant/(93*5mg) = 2322.58 plants

To find the number of plants Mr. Frank could fertilize, we need to divide the total amount of fertilizer by the amount of fertilizer needed per plant.

First, we need to convert 1.08 kilograms to milligrams, as the amount of fertilizer needed per plant is given in milligrams.

1 kilogram is equal to 1,000,000 milligrams, so 1.08 kilograms would be 1.08 x 1,000,000 = 1,080,000 milligrams.

Now that we have the total amount of fertilizer in milligrams, we can divide it by the amount of fertilizer needed per plant to find the number of plants Mr. Frank could fertilize.

1,080,000 milligrams / 93 milligrams = 11612.9032

Since we can't have a fractional number of plants, we will round down to the nearest whole number.

Therefore, Mr. Frank could fertilize approximately 11,612 plants with 1.08 kilograms of fertilizer.
