Decimal Point Movement: Positioning 7 as Tenths Digit in 1.672

To solve this problem, we'll follow these steps:

• Step 1: Understand the given number 1.672.
• Step 2: Recognize the current position of the digit 7 as the hundredths place.
• Step 3: Move the decimal point one position to the right.
• Step 4: Verify that the digit 7 now occupies the tenths place.

Now, let's work through each step:
Step 1: The given number is $1.672$, with digits positioned as follows - 1 in the units place, 6 in the tenths place, 7 in the hundredths place, and 2 in the thousandths place.
Step 2: We need 7 to be in the tenths place, so we need to shift our understanding of the number.
Step 3: By moving the decimal point one place to the right, the number becomes $16.72$.
Step 4: In $16.72$, digit 7 is now correctly positioned in the tenths place, preceded by the digit 6 in the units place.

Therefore, the number after moving the decimal point so that 7 becomes the tenths digit is $\boxed{16.72}$.
