Hundredth and Thousandth
Let us study the place value of 7 in these numbers.
If 7 moves one more column to the right its place value becomes
7 ÷ 100 = \(\frac{7}{100}\) = 7 hundredths or 0.07
Fractions with denominators 10, 100, and 1,000 are called decimal fractions.
Example: Decimal part and whole number part
A decimal number consists of two parts
