1 answer

To find \( 907.907 - 709.709 \), you simply subtract the two numbers:

\[ 907.907 - 709.709 \]

Align the numbers by the decimal point for clarity:

  907.907
- 709.709

Now, perform the subtraction starting from the right:

  1. Subtract the thousandths place: \( 7 - 9 \) requires borrowing. We take 1 from the hundredths place (0 becomes 9), so we have 17 - 9 = 8.
  2. Subtract the hundredths place: \( 0 - 0 = 0 \).
  3. Subtract the tenths place: \( 9 - 7 = 2 \).
  4. Subtract the units place: \( 7 - 9 \) again requires borrowing. We take 1 from the hundreds place (0 becomes 8), so \( 17 - 9 = 8 \).
  5. Subtract the hundreds place: \( 8 - 7 = 1 \).

Putting it all together:

\[ 907.907 - 709.709 = 198.198 \]

Thus, the answer is:

\[ \boxed{198.198} \]
