1. Observe this vertical pose. What do you find?

My summary:

In the decimal part of a number, starting from a certain digit, one digit or several digits appear repeatedly in sequence. Such decimals are called recurring decimals.

If two numbers are divided and the integer quotient cannot be obtained, what will happen to the resulting quotient?

What we found

A decimal with a finite number of digits in the decimal part is called a finite decimal. For example, 0.9375 is a finite decimal. A decimal with infinite digits in the decimal part is called a finite decimal.

For example, 0.214857142857...is an infinite decimal.

Consolidate and expand:
