Answer 1

He can, if he subtracts the 1/10 from 10/10 or 1 he will have 9/10.. hope it helped

Answer 2

Answer:

Eric can use this method, it's totally correct.

Step-by-step explanation:

According to Eric's opinion, 9/10is 1/10 less than 10/10 or 1 mile.

So, to prove that, he is going to subtract 1 mile and 9/10, to obtain 1/10 back. Let's see if he's right

$1-\frac{9}{10}=\frac{10-9}{10} =\frac{1}{10}$

You can observe that Eric is actually right, he can subtract 9/10 from 1 mile, and that operation will return 1/10 back.

Therefore, Eric can use this method, it's totally correct.
