The decimal number 0.75 is a common fraction that can be expressed in simplest form. In this article, we will explore how to convert 0.75 to a fraction, simplify it, and understand its practical applications.
Converting 0.75 to a Fraction
To convert 0.75 to a fraction, we can write it as 75/100. This is because the decimal point separates the whole number from the fractional part, and the denominator represents the total number of equal parts.
Simplifying the Fraction
Now that we have 75/100, we can simplify the fraction by finding the greatest common divisor (GCD) of both numbers. The GCD of 75 and 100 is 25. By dividing both the numerator and denominator by 25, we get:
75 ÷ 25 = 3 100 ÷ 25 = 4
So, the simplified fraction of 0.75 is 3/4.
