Question

el 15% del 40% del 20% de que numero es el 40% del 5% de 600

Answer 1

Primero resolvemos:

40% del 5% de 600

40% × 5% × 600

$\frac{40}{100}$×$\frac{5}{100}$×600

$\frac{2}{5}$×$\frac{1}{20}$×600

$\frac{2x1x600}{5x20}$

$\frac{1200}{100}$

12

Luego:

El 15% del 40% del 20% de x = 12

15% × 40% × 20% × x = 12

$\frac{15}{100}$×$\frac{40}{100}$×$\frac{20}{100}$×x = 12

$\frac{3}{20}$×$\frac{2}{5}$×$\frac{1}{5}$×x = 12

x = 12 × $\frac{20x5x5}{3x2x1}$

x = $\frac{12x20x5x5}{3x2x1}$

x = $\frac{6000}{6}$

x = 1000

∴ Respuesta = 1000
