Answer:
A. 8 rows.
B. 3 toy soldiers.
Explanation:
We are told that Meliza has 43 toys soldiers, she line them up 5 to fight imaginary zombies .
A. Let us find the greatest multiple of 5 from 43.
Multiples of 5 are: 5,10, 15, 20, 25, 30, 35, 40, 45,..
We can see the greatest multiple of 5 from 43 is 40.
Let us divide 40 by 5 to find the number of rows that Meliza can make.

Therefore, Meliza can make 8 rows of 5 from 43 toy soldiers.
B. To find the number of soldier in last row we will subtract 40 from 43.

Therefore, the number of toy soldiers in last row will be 3 soldiers.
