?(1 point)
$$

1 answer

To calculate \( 3.125 - 1.6 \), we can rewrite \( 1.6 \) as \( 1.600 \) to align the decimal places:

\[ \begin{array}{r} 3.125 \

  • 1.600 \ \hline \end{array} \]

Now, subtract the numbers column by column:

  • In the thousandths place: \( 5 - 0 = 5 \)
  • In the hundredths place: \( 2 - 0 = 2 \)
  • In the tenths place: \( 1 - 6 \) requires borrowing. We will borrow 1 from the units place, which makes the 3 a 2. So it becomes \( 11 - 6 = 5 \).
  • In the units place: \( 2 - 1 = 1 \)

Putting it all together, we have:

\[ \begin{array}{r} 3.125 \

  • 1.600 \ \hline 1.525 \ \end{array} \]

Thus, the answer is

\[ \boxed{1.525} \]
