Solution:
The ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16.
Let say number of packages of corn tortillas = 7k
then total number of packages = 16k
number of packages of flour tortillas = 16k - 7k = 9k
7k corn tortillas
9k flour tortillas
7 and 9 are co prime numbers
Hence flour tortillas must be a multiple of 9
like
9 , 18 , 27 .. etc
