Calcular la cuarta proporcional de 2, 3 y 4; 10, 20 y 30; 25, 30 y 50.

Answer 1

$\frac{2}{3} =\frac{4}{x}\\\\x= \frac{3(4)}{2}\\ \\x = \frac{12}{2}\\ \\x = 6\\\\\\\\\frac{10}{20} = \frac{30}{x}\\  \\x =\frac{20(30)}{10}\\\\x=\frac{600}{10}\\\\x = 60\\\\\\\\\frac{25}{30} = \frac{50}{x}\\  \\x =\frac{50(30)}{25}\\\\x=\frac{1500}{25}\\\\x = 60$
