Answer 1

subiectul 2

1

$\frac{3x - 15}{18} = \frac{48}{18} \\ 3x - 15 = 48 \\ 3x = 48 + 15 \\ 3x = 63 \\ x = \frac{63}{3} = 21b$

3

$\frac{2 + 3 + 4}{2 \times 3 + 3 \times 3 + 4 \times 3 } = \frac{9}{27} = \frac{1}{3} a$

$\frac{3 0 \times 2}{3} = \frac{60}{3} = 20$

3

$\frac{15}{100} \times 400 = \frac{15 \times 400}{100} = \frac{6000}{100} = 600$
