Question

Dacă 16a=28b si a/b = 35/x determinati x​

Answer 1

$\frac{a}{b} = \frac{35}{x} \implies \frac{16a}{16b} = \frac{35 \times 16}{16x} \\ \\ \frac{28b}{16b} = \frac{35 \times 16}{16x} \implies 28 = \frac{35}{16x} \\ \\ 16x = \frac{35}{28} \implies \: x = \frac{35}{28} \times \frac{1}{16} = \bold{\frac{5}{64} }$
