[tex] \frac{480}{100} [/tex]
Because the two zeros mean move the decimal point two times to the right.
[tex] \frac{48}{10} [/tex]
Or it can also be 48/10 because the zeros means move the decimal point to the left. since everyone you divide by 10 you move the decimal point one time to the left, and every time you multiply by 10 you move the decimal point to the right.
