What is Tenths and hundredths?

Definition 25.1 Primary & Middle School Mathematics · Chapter 25 — Tenths and Hundredths

Cutting a unit into 1010 equal parts gives tenths, 110\frac{1}{10}; cutting each tenth into 1010 again gives hundredths, 1100\frac{1}{100}. So

1=1010=100100,110=10100.1 = \frac{10}{10} = \frac{100}{100}, \qquad \frac{1}{10} = \frac{10}{100}.
The hundred-square: ten columns of ten cells. One column is a tenth, one cell a hundredth.
The hundred-square: ten columns of ten cells. One column is a tenth, one cell a hundredth.

Examples

Example 25.2

Shading 33 columns and 77 extra cells of the hundred-square shades

310+7100=30100+7100=37100\frac{3}{10} + \frac{7}{100} = \frac{30}{100} + \frac{7}{100} = \frac{37}{100}

of the square — thirty-seven hundredths.
