## Basic College Mathematics (10th Edition)

Since the prefix T means one trillion, 1Tm is one trillion meters. Use the unit fractions from the earlier exercises to convert Tm to Gm and Mm. $1Tm=1Tm\times\frac{1,000,000,000,000m}{1Tm}\times\frac{1Gm}{1,000,000,000m}= 1,000Gm$ $1Tm=1Tm\times\frac{1,000,000,000,000m}{1Tm}\times\frac{1Mm}{1,000,000m}= 1,000,000Mm$
