Respuesta :
The smallest number that m*n could be is 33 because the smallest m stands for 11 and the smallest n stands for 3, so 11*3=33.
The largest number that m-n could be is 16 because the largest m stands for 19 and the smallest n stands for 3, so 19-3=16
The largest number that m-n could be is 16 because the largest m stands for 19 and the smallest n stands for 3, so 19-3=16
Less: M=11 N=3
Since M has to be greater than 10, but less than twenty, the smallest number it could be would be 11. The same goes for 3.
More: M=19 N=9
It has to be less than 20, so M cannot be 20. N also has to be less than 10.
