What can you say about the prime factorisation of denominator of 15.25?

Answer 1

Answer:

2,2

Step-by-step explanation:

To find out the prime factorization of the denominator of 15.25, we need to find the denominator first.

Steps to convert the decimal value into a fraction:

1) Let the decimal value be divided by 1.

     15.25 / 1

2) Multiply numerator and denominator with 100 to remove the decimal points.

     (15.25 x 100) / (1 x 100) = 1525/100 = 61/4

So, the required denominator is 4.

Prime factorization of a number is the factors that are prime. For example, the prime factorization of 15 = 3 x 5.

The prime factorization of 4 = 2 x 2

So the prime factors are 2, 2
