Question

exercitiul 3, punctele a, b, c, d! multumesc

Answer 1

$\frac{x}{y} = 8$

$a) \frac{x}{3y} = \frac{1}{3} \times \frac{x}{y} = \frac{1}{3} \times 8 = \frac{8}{3}$

$b) \frac{4x}{y} = 4 \times \frac{x}{y} = 4 \times 8 = 32$

$c) \frac{5x}{8y} = \frac{5}{8} \times \frac{x}{y} = \frac{5}{8} \times 8 = 5$

$d) \frac{0.2x}{y} = 0.2 \times \frac{x}{y} = \frac{2}{10} \times 8 = \frac{1}{5} \times 8 = \frac{8}{5}$

Answer 2
