Answer:
2789 , 180 mg
Step-by-step explanation:
Given:
Mr. Frank has 1.06 kilograms of fertilizer for the plants in his nursery.
He wants every plant to get 95 mg of fertilizer 2 times each year.
Question asked:
What is the number of plants he could fertilize with that amount?
How much fertilizer will he have left over?
Solution:
First of all convert 1.06 kilograms into milligram,
1 kg = 1000000 mg
1.06 kg = 1060000 mg
He wants to fertilized 2 times each year.
Each year, he uses fertilizer for one plant = 2 [tex]\times[/tex] 95 = 190 mg
190 mg fertilizer is used to fertilize number of plant = 1
1 mg fertilizer is used to fertilize number of plant = [tex]\frac{1}{190}[/tex]
1060000 mg fertilizer is used to fertilize number of plant = [tex]\frac{1}{190} \times1060000=\frac{1060000}{190} =5578\frac{180}{190}[/tex]
That means, 5578 mg used for fertilizing the plant twice a year and 180 mg is left over.
Now, to find the number of plants he could fertilize, we will divide 5578 by 2 because it is twice the number of plant as calculated above:-
5578 [tex]\div[/tex] 2 = 2789 plants
Thus, total 2789 plants could be fertilized and 180 mg will be left over.
