Convert the mixed repeating (recurring) decimal number 2.458. Turn it into a reduced (simplified) improper fraction, into a mixed number and write it as a percentage. Calculate other equivalent fractions to the decimal number, by expanding

Convert 2.458

1. Write the mixed repeating (recurring) decimal number as a percentage.

Approximate to the desired number of decimal places (14):

2.458 ≈ 2.45888888888889

Multiply the number by ^{100}/_{100}.

The value of the number does not change when multiplying by ^{100}/_{100}.

Note: ^{100}/_{100} = 1

2.45888888888889 =

2.45888888888889 × ^{100}/_{100} =

^{(2.45888888888889 × 100)}/_{100} =

^{245.888888888889}/_{100} =

245.888888888889% ≈

245.89%

(rounded off to a maximum of 2 decimal places)

In other words:

Approximate to the desired number of decimal places...

The numerator and the denominator are coprime numbers (no common prime factors, GCF = 1). So, the fraction cannot be reduced (simplified): irreducible fraction.

4. The fraction is an improper one, rewrite it as a mixed number (mixed fraction):

A mixed number = an integer number and a proper fraction, of the same sign.

Example 1: 2 ^{1}/_{5}; Example 2: - 1 ^{3}/_{7}.

A proper fraction = the numerator is smaller than the denominator.

2,213 ÷ 900 = 2, remainder = 413 =>

2,213 = 2 × 900 + 413 =>

^{2,213}/_{900} =

^{(2 × 900 + 413)} / _{900} =

^{(2 × 900)} / _{900} + ^{413}/_{900} =

2 + ^{413}/_{900} =

2 ^{413}/_{900}

^{2,213}/_{900}: Equivalent fractions.

The above fraction cannot be reduced.

That is, it has the smallest numerator and denominator possible.

By expanding it we can build up equivalent fractions.

(Multiply the numerator & the denominator by the same number).

Learn how to turn a decimal number into a fraction and a percentage. Steps.

1. How to write the number as a percentage:

Multiply the number by 100. Then add the percent sign, %.

2. How to write the number as a fraction:

Write down the number divided by 1, as a fraction.

Turn the top number into a whole number: multiply both the top and the bottom by the same number.

Reduce (simplify) the above fraction to the lowest terms, to its simplest equivalent form, irreducible. To reduce a fraction divide the numerator and the denominator by their greatest (highest) common factor (divisor), GCF.

If the fraction is an improper one, rewrite it as a mixed number (mixed fraction).

Calculate equivalent fractions. By expanding it we can build up equivalent fractions: multiply the numerator & the denominator by the same number.
