Question

Allie wants to subtract 341-97 mentally. first she adds 3 to 97 to get 100. what should Allie's next step be? what is the difference?​

Answer 1

244.

Explanation:

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
`3+341=344`.

Now, we will subtract 100 from 344 as:

`344-100=244`

Therefore, the difference of both numbers would be 244.
