The ratio between 1 0 million and1100 million is 10.

1 000000 is 8 digits, 1000000 is 9 digits, and the propulsion rate between two adjacent units is10.

Between two units of measurement of the same kind, if the higher unit is several times that of the lower unit, then this value is called the forward speed between these two units.

Decimalization is based on two principles: decimal and decimal, that is, all numbers are represented by 10 basic symbols, which are full of decimals. At the same time, the same symbol represents different values in different positions, so the position of the symbol is very important.

There are decimal, binary, decimal, sexagesimal and so on. Now compare the commonly used decimal and binary.

Decimal number is a number system based on 10, which consists of ten basic numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. Decimalization is based on two principles: decimal and decimal, that is, all numbers are represented by 10 basic symbols, which are full of decimals. At the same time, the same symbol represents different values in different positions, so the position of the symbol is very important. Decimalization is mainly used in daily life.

Binary is a digital system widely used in computing technology. Binary data are numbers represented by 0 and 1. Its cardinal number is 2, the carry rule is "every binary is one", and the borrowing rule is "borrow one as two". Binary is mainly used for computer operation.
