Question

what fraction is equivalent to 0.081

Answer 1

The 1 at the end of the number is in which decimal place?

Answer 2

hundreths?

Answer 3

\[0.081=\frac{8.1}{100}=\frac{81}{1000}\]

Answer 4

The zero to the right of the decimal point is tenths.
The 8 is hundredths.
The 1 is thousandths.
So the number is 81 thousandths.

Just write that as a fraction: \( \dfrac{81}{1000} \)

Answer 5

Since 81 = 3 * 3 * 3 * 3,
and 1000 = 2 * 2 * 2 * 5 * 5 * 5,
the two numbers have no common factors, so the fraction is reduced.

Answer 6

You can break it down by resorting to going through the tens:
\[0.081=\frac{0.081}{1}=\frac{0.81}{10}=\frac{8.1}{100}=\frac{81}{1000}\]
