A decimal that terminates or stops after a finite number of decimal places is a terminating decimal.

Among the choices, except 0.055, all are repeating decimals.

So, 0.055 is a terminating decimal.

The price of three books = $42.85.

Price of each book = 42.853.

The price of a book is $14.28333...

It is a repeating decimal.

When the same block of digits in a decimal repeats without end, the decimal is called a repeating decimal.

0.114114114...

In the number 114 is repeating with out end.

The number is a repeating decimal number.

When a digit or sequence of digits keep repeating, it is a repeating decimal.

For 45, when 4 is divided by 5 the quotient is 0.8.

For 38, when 3 is divided by 8 the quotient is 0.375.

For 310, when 3 is divided by 10 the quotient is 0.3.

For 112, when 1 is divided by 12, the quotient is 0.08333. . . and the digit 3 is repeating.

Therefore, 112 is a repeating decimal.

12.6 ÷ 3

Divisor = 3 and dividend = 12.6.

Quotient = 4.2. It is a terminating decimal.
