(sqrt (1,96)-sqrt (0,64))/(sqrt (1,44)) __ A) 0,1 B) 0,25 C) 0.4 D) 0,5 E) 0,75

To solve the expression \(\frac{\sqrt{1.96} - \sqrt{0.64}}{\sqrt{1.44}}\), we need to evaluate each square root individually.<br /><br />First, we find the square roots:<br />\[<br />\sqrt{1.96} = 1.4<br />\]<br />\[<br />\sqrt{0.64} = 0.8<br />\]<br />\[<br />\sqrt{1.44} = 1.2<br />\]<br /><br />Next, we substitute these values back into the original expression:<br />\[<br />\frac{1.4 - 0.8}{1.2}<br />\]<br /><br />Now, we perform the subtraction in the numerator:<br />\[<br />1.4 - 0.8 = 0.6<br />\]<br /><br />Finally, we divide by the denominator:<br />\[<br />\frac{0.6}{1.2} = 0.5<br />\]<br /><br />Thus, the correct answer is:<br />D) 0.5
