Score: \( 4 / 16 \) Answered: \( 4 / 16 \) Question 7 Add: \( 5.577+475.3+6.64 \) \( \square \gg \)

Calculate the value by following steps: - step0: Calculate: \(5.577+475.3+6.64\) - step1: Add the numbers: \(487.517\) To add the numbers \( 5.577 \), \( 475.3 \), and \( 6.64 \), we proceed as follows: 1. **Align the numbers by their decimal points:** \[ \begin{array}{r} 5.577 \\ 475.300 \\ + 6.640 \\ \hline \end{array} \] 2. **Add the numbers column by column:** - Starting from the rightmost column (thousandths): - \( 7 + 0 + 0 = 7 \) - Next column (hundredths): - \( 7 + 0 + 4 = 11 \) (write down 1 and carry over 1) - Next column (tenths): - \( 5 + 3 + 6 + 1 = 15 \) (write down 5 and carry over 1) - Finally, the whole numbers: - \( 4 + 5 + 1 = 10 \) (write down 0 and carry over 1) - \( 1 \) from the carry over. 3. **Combine the results:** \[ 487.517 \] Thus, the sum of \( 5.577 + 475.3 + 6.64 \) is \( 487.517 \).
