Question

The number below is written in expanded notation. (See page 24-25)
(1 × 1,000) + (5×100) + (9x1) + (7x0.1) +
(4 × 0.01)
How is this number written in standard form

Answer 1

To write the number in standard form, you can calculate the value of each term in the expanded notation:

1. \(1 \times 1,000 = 1,000\)
2. \(5 \times 100 = 500\)
3. \(9 \times 1 = 9\)
4. \(7 \times 0.1 = 0.7\)
5. \(4 \times 0.01 = 0.04\)

Now, add these values together:

\[
1,000 + 500 + 9 + 0.7 + 0.04 = 1,000 + 500 + 9 + 0.7 + 0.04 = 1,509.74
\]

So, the number written in standard form is **1,509.74**.
