John said he can find 38×10 by adding a 0 to the end of 38 to get 380. John finds 46.52×10 using the same method and gets 46.520

Answer: See explanation

Step-by-step explanation:

John said he can find 38×10 by adding a 0 to the end of 38 to get 380. John finds 46.52×10 using the same method and gets 46.520.

For the first one that is, 38 × 10 = 380, John is correct. For the second one, that is, 46.52 × 10 = 46.520. John is incorrect. In this case, the first one is correct because John was multiplying by a whole number.

For the second one involving a decimal, John could have shifted the decimal point one place to the right and not add 0 to the end. Then he will get:

46.52 × 10 = 465.2
