5-47.

The average distance from the earth to the moon is $3.844\times10^8$ meters. If the length of the average pencil is $1.8 × 10^{−1}$ meters, approximately how many pencils would need to be connected together to reach the moon? Use appropriate precision in your answer.

This would require dividing these two numbers in scientific notation.
Review the Math Notes box in Lessons 1.3.1 and 1.3.2.

$\frac{3.844 \times 10^{8}}{1.8 \times 10^{-1}}$
