The value of the digit 7 in the number 17.48 is 10 times the value of the digit 7 in which number?
Problem 2
Sonya is trying to solve for the missing value in the equation 93.6 × _____ = 93,600. Sonya claims that the answer is 100 because there are two zeros at the end of 93,600 and multiplying by ten results in an extra 0 at the end of the number, so multiplying by 100 would results in two zeros at the end of the number.
Explain why Sonya’s reasoning is incorrect.
