Convert the decimal number 18.1. 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 18.1

1. Write the number as a percentage.

Multiply the number by ¹⁰⁰/₁₀₀

Note: ¹⁰⁰/₁₀₀ = 1

The value of the number does not change when multiplying by ¹⁰⁰/₁₀₀

18.1 =

18.1 × ¹⁰⁰/₁₀₀ =

^{(18.1 × 100)}/₁₀₀ =

^1,810/₁₀₀ =

1,810%

In other words:

Multiply the number by 100...

... And then add the percent sign, %

18.1 = 1,810%

2. Write the number as an improper fraction.

18.1 can be written as an improper fraction.

The numerator is larger than or equal to the denominator.

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

18.1 = ^18.1/₁

Turn the top number into a whole number.

Multiply both the top and the bottom by the same number.

This number is: 10.

1 followed by as many 0-s as the number of digits after the decimal point.

^18.1/₁ =

^{(18.1 × 10)}/_{(1 × 10)} =

¹⁸¹/₁₀

3. Reduce (simplify) the fraction above: ¹⁸¹/₁₀
(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.

Factor both the numerator and the denominator (prime factorization).

181 is a prime number, it cannot be factored into other prime factors

10 = 2 × 5

Prime factorization: break numbers down to prime factors, online calculator

Calculate the greatest (highest) common factor (divisor), GCF.

Multiply all the common prime factors by the lowest exponents.

But, the numerator and the denominator have no common factors.

GCF (181; 2 × 5) = 1

Calculate the greatest (highest) common factor (divisor), GCF, online calculator

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.

181 ÷ 10 = 18, remainder = 1 =>

181 = 18 × 10 + 1 =>

¹⁸¹/₁₀ =

^{(18 × 10 + 1)} / ₁₀ =

^{(18 × 10)} / ₁₀ + ¹/₁₀ =

18 + ¹/₁₀ =

18 ¹/₁₀

¹⁸¹/₁₀: Equivalent fractions.

The above fraction cannot be reduced.

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

By expanding it we can build up equivalent fractions.

Multiply the numerator & the denominator by the same number.

Example 1. By expanding the fraction by 3:

¹⁸¹/₁₀ = ^{(181 × 3)}/_{(10 × 3)} = ⁵⁴³/₃₀

Example 2. By expanding the fraction by 7:

¹⁸¹/₁₀ = ^{(181 × 7)}/_{(10 × 7)} = ^1,267/₇₀

Of course, the above fractions are reducing...

... to the initial fraction: ¹⁸¹/₁₀
