    The digit that is one tenth of the number is 2.

    Step-by-step explanation:

    Let be x = 3\times 1000 + 2\times 100 + 7\times 10 + 5\times 1 + 2\times \frac{1}{10}+5\times \frac{1}{100}, the digit that is one tenth of the number shown in expanded form is that whose numerator that multiplies it is 1 and denominator is 10. Therefore, the digit that is one tenth of the number is 2.
