Marcel said he can find 52*10 by adding a 0 to the end of 52 to get 520. Marcel finds 74.26 * 10 using the same method and gets 74.260

The answer is incorrect.

Step-by-step explanation:

What Marcel said is that if you multiply a number times 10 it is only necessary to add a zero at the end. However, with the number 74.26, it is necessary to move the dot instead of adding a zero due to this, the correct answer is 742.6 and not 74.260, which is the same as the original value (74.2.)
