To convert the decimal \(0.38\) to a fraction, follow these steps:
-
Write the decimal as a fraction. Since there are two digits after the decimal point, we can write: \[ 0.38 = \frac{38}{100} \]
-
Next, simplify the fraction \( \frac{38}{100} \) by finding the greatest common divisor (GCD) of the numerator and the denominator. The GCD of \(38\) and \(100\) is \(2\).
-
Divide both the numerator and the denominator by their GCD: \[ \frac{38 \div 2}{100 \div 2} = \frac{19}{50} \]
Therefore, the decimal \(0.38\) as a simplified fraction is: \[ \boxed{\frac{19}{50}} \]
