For a complete lesson on converting decimals to fractions, go to http://www.MathHelp.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students use the place value chart to convert decimals to fractions or mixed numbers. The given decimals are taken to the tenths, hundredths, thousandths, or ten-thousandths places, and the resulting fractions or mixed numbers must sometimes be reduced to lowest terms. For example, the decimal 0.4 means 4 tenths, or 4/10, which reduces to 2/5.
