# How do you write 0.143 in scientific notation?

Dec 30, 2015

See solution below.

#### Explanation:

0.143 = 1.43 • ${10}^{-} 1$

The general rule is move the decimal so that the number in question is 0 ≤ x ≤ 10. Depending on how many places you move the decimal, and in what direction, you will write the exponent differently. In your example, I moved the decimal one unit to the right which makes a "  • 10^-1 "

Hopefully this makes sense.
