Question

mrs. green puts 57 cans on a shelf. she puts an equal number of cans in each of the 9 rows and puts 3 cans in the last row. how many cans does she put in each of the 9 rows?

Answer 1

Since she has 57 cans and 3 cans are allready devoted to the last row u must do 57-3 in or to get 54 cans total leftover. Then divide the number 54 by 9 since there are nine rows.so i think there will be six cans on each row of the shelf!
 

Answer 2

57-3= 54
54/9= 6
there can be 6 cans on each of the 9 rows
