Question

1pe x egal 2pe 10egal3pe y egal z pe 20​

Answer 1

$\frac{1}{x} = \frac{2}{10} = \frac{3}{y} = \frac{z}{20}$

$a)10 = x \times 2$

$x \times 2 = 10$

$x = \frac{10}{2}$

$x = 5$

$b)y \times 2 = 10 \times 3$

$y \times 2 = 30$

$y = \frac{30}{2}$

$y = 15$

$c) \frac{3}{15} = \frac{z}{20}$

$4 \times 3 = 3z$

$12 = 3z$

$3z = 12$

$3z = \frac{12}{3}$

$z = 4$

(( $x = 5$

$y = 15$

$z = 4$))
