Question

Escreva a forma irredutível a razão entre:

a) 10 km e 15 km b) 40 kg e 120 kg

c) 2 m e 70 km d) 1800 g e 3kg

Answer 1

.
$a) \\ \frac{10km}{15km} = \frac{2}{3} \\ b) \\ \frac{40kg}{120kg} = \frac{1}{3} \\ c) \\ \frac{2m}{70km} = \frac{2m}{70000m} = \frac{1}{3.500} \\ d) \\ \frac{1800g}{3kg} = \frac{1800g}{3000g} = \frac{3}{5}$
