Decimal Place Value Relationships

Decimal Place Value Relationships is a skill on Pengi from Lesson 3: Decimals to Thousandths in enVision, Mathematics, Grade 5.

Key Concepts

Property The value of a digit in a decimal number is $10$ times the value of the digit to its right and $\frac{1}{10}$ the value of the digit to its left.

Examples In the number $0.22$, the value of the $2$ in the tenths place ($0.2$) is 10 times the value of the $2$ in the hundredths place ($0.02$). In the number $0.888$, the value of the $8$ in the hundredths place ($0.08$) is $\frac{1}{10}$ the value of the $8$ in the tenths place ($0.8$). In $0.055$, the value of the $5$ in the hundredths place ($0.05$) is 10 times the value of the $5$ in the thousandths place ($0.005$).

Explanation Our number system is based on powers of ten. As you move from left to right on the place value chart, the value of each position is one tenth of the value of the position to its left. This means a digit in one place is ten times as great as the same digit in the place to its right. This relationship holds true for both whole numbers and decimals.
