We have been given that Allie wants to subtract 341-97 mentally. First she adds 3 to 97 to get 100. We are asked to determine Allie's next step and the difference of both numbers.
Allie's next step would be add 3 to 341 because adding same quantity to both numbers will keep the ratio same.
After adding 3 to 341 Allie would get .
Now, we will subtract 100 from 344 as:
Therefore, the difference of both numbers would be 244.
