All pure decimals are less than 1 ()

Decimals whose integral part is zero are called pure decimals. For example, 0.123, 0.99, 0.114 and 0.15256 are pure decimals. Pure decimals are less than 1
The form of ××× with decimals is the number with several numbers (not "0") before the decimal point
Such as: 1.1, 1.254.5.368, etc
0.12121212…… It's a pure cyclic decimal. Of course, it's also a pure decimal
That's right
