II. Simplifying 25/1500: Finding the Greatest Common Divisor (GCD)

Simplifying a fraction means reducing it to its lowest terms. This is achieved by finding the greatest common divisor (GCD) of the numerator (25) and the denominator (1500). The GCD is the largest number that divides both the numerator and denominator without leaving a remainder.

Let's find the GCD of 25 and 1500. We can use the prime factorization method:

• Prime factorization of 25: 5 x 5 = 5²
• Prime factorization of 1500: 2 x 2 x 3 x 5 x 5 x 5 = 2² x 3 x 5³

The common factors are 5 x 5 = 25. Therefore, the GCD of 25 and 1500 is 25.

To simplify the fraction, we divide both the numerator and the denominator by the GCD:

25/1500 = (25 ÷ 25) / (1500 ÷ 25) = 1/60

Therefore, the simplified form of 25/1500 is 1/60. This simplified fraction is much easier to work with and understand.

III. Converting 1/60 to a Percentage

Converting a fraction to a percentage is a fundamental skill. To convert 1/60 to a percentage, we perform the following calculation:

(1/60) x 100% = 1.666...%

This can be rounded to 1.67%. This means that 25 out of 1500 represents approximately 1.67% of the whole.
