Answer: 5 bags
Step-by-step explanation:
Given : Mr. Daniel has [tex]1\dfrac{2}{3}[/tex] acres of land in which he plans to fertilize.
Here [tex]1\dfrac{2}{3}=\dfrac{3(1)+2}{3}=\dfrac{5}{3}[/tex]
Each bag of fertilizer covers [tex]\dfrac{1}{9}[/tex] of an acre .
By using UNITARY METHOD ,the number of bags of fertilizer required for [tex]\dfrac{5}{3}[/tex] of an acre :-
[tex]\dfrac{5}{3}\div\dfrac{1}{9}=\dfrac{5}{3}\times9=15\text{ bags}[/tex]
If he bought 20 bags of fertilizer , then he left over = 20 -15 = 5 bags
hence, he left over with 5 bags of fertilizer.
