What is 4.5 as a Fraction?
Answer – 4.5 is written as 9/2 as a fraction.
Explanation:
4.5 can be written as 45/10.
This fraction can be further simplified by finding the greatest common divisor (GCD) and dividing the fraction further with it.
GCD is the largest number that divides two or more numbers without leaving a remainder.
One way to find the GCD of a number is by the prime factorization method. In this, both the numerator and denominator are prime factorized, as shown below:
- 45 = 3 x 3 x 5
- 10 = 2 x 5
The common prime factor for both numbers is 5. Therefore, the GCD is 5.
The next step is to divide both the numerator and denominator by the GCD.
- 45÷5/10÷5 = 9/2.
This is the simplified form of the fraction.
Thus, 4.5 can be written as 9/2 as a fraction.
