Question

x/3 = 7/2 b 5/12 = x/9 c 7/8 = 2/3 * x b 12/x = 11 e 3/x * 2 = 5/6 F 3 x / 2 = 8 ​

Answer 1

Explicație pas cu pas:

$\dfrac{x}{3} = \dfrac{7}{2} \implies x = \dfrac{3 \cdot 7}{2} = \dfrac{21}{2}$

$\dfrac{5}{12} = \dfrac{x}{9} \implies x = \dfrac{5 \cdot 9}{12} = \dfrac{15}{4}$

$\dfrac{7}{8} = \dfrac{2}{3}x \implies x = \dfrac{7 \cdot 3}{2 \cdot 8} = \dfrac{21}{16}$

$\dfrac{3x}{2} = 8 \implies x = \dfrac{2 \cdot 8}{3} = \dfrac{16}{3}$
