9/15 is a terminating decimal

Given :

The fraction 9/15

To find :

To justify 9/15 is a terminating decimal

Concept :

\displaystyle\sf{Fraction =  \frac{Numerator}{Denominator} }

A fraction is said to be terminating if prime factorisation of the denominator contains only prime factors 2 and 5

If the denominator is of the form

 \sf{Denominator =  {2}^{m}  \times  {5}^{n} }

Then the fraction terminates after N decimal places

Where N = max { m , n }

Solution :

Step 1 of 3 :

Write down the given fraction

The given fraction is

\displaystyle \sf{  =  \frac{9}{15}  }

Step 2 of 3 :

Simplify the given fraction

\displaystyle \sf{    \frac{9}{15}  }

\displaystyle \sf{  =  \frac{3}{5}  }

Step 3 of 3 :

Justify 9/15 is a terminating decimal

Denominator = 5

Since the prime factorisation of the denominator contains only prime factors as 5

So the given rational number is terminating

Since the exponent of 5 = 1

Hence the given rational number terminates after 1 decimal places

Hence 9/15 is a terminating decimal
