A terminating decimal is a decimal with a certain number of digits to the right of the decimal point.

Informally, non-terminating decimals are easily understood, because it is clear that a real number can be approximated to any required degree of precision by a terminating decimal.

We exemplify these procedures using the matrix This matrix, in fact, has the determinant 100; since its elements are integers, the elements of the reciprocal will be terminating decimals.

Irrational Numbers Page 6 Summary Rational Numbers can be written as fractions All terminating decimals can be written as fractions.

If the repetend is a zero, this decimal representation is called a terminating decimal rather than a repeating decimal, since the zeros can be omitted and the decimal terminates before these zeros.

I can use decimal notation and recognise that each terminating decimal is a fraction I can order decimals I can convert simple fractions of a whole to percentages of the whole and vice versa.

Any repeating decimal not of the form described above can be written as a sum of a terminating decimal and a repeating decimal of one of the two above types (actually the first type suffices, but that could require the terminating decimal to be negative).
