To write \( 2.7 \times 10^7 \) in decimal notation, you move the decimal point 7 places to the right:

1. Start with \( 2.7 \).
2. Move the decimal point 7 places to the right:
- Moving 1 place: \( 27.0 \) (1)
- Moving 2 places: \( 270.0 \) (2)
- Moving 3 places: \( 2700.0 \) (3)
- Moving 4 places: \( 27000.0 \) (4)
- Moving 5 places: \( 270000.0 \) (5)
- Moving 6 places: \( 2700000.0 \) (6)
- Moving 7 places: \( 27000000.0 \) (7)

So, \( 2.7 \times 10^7 \) in decimal notation is \( 27000000 \).
