Q:
# How Are Decimals Written in Expanded Form?

**A decimal number is written in expanded form by multiplying each individual number by the value of the decimal place that it occupies.** Expanded form is rarely used, as both decimal form and mixed form are more convenient and practical forms of a non-whole number.

For example, the number 57.5 written in expanded form would be equal to (5 * 10) + (7 * 1) + (5 * 0.1). Each number is multiplied by its location value. The 7 is in the one's column, so it is represented by 7 * 1 in a bracket. If all of the individual brackets in the expanded form are evaluated and the results are added, the original number in decimal notation will be obtained.
