Answer 1

PROBLEMA 1

$\frac{3.9}{x} = \frac{5}{3.4} \\3.9 \times 3.4 = 5x \\ 13.26 = 5x \\ \frac{13.26}{5} = x \\ 2.652 = x$

PROBLEMA 2

$\frac{3.7}{BE} = \frac{8}{5} \\ 3.7 \times 5 = 8 \times BE \\ 18.5 = 8 \times BE \\ \frac{18.5}{8} = BE \\ 2.3125 = BE$

$\frac{5}{3.9} = \frac{3}{ED} \\ 5 \times ED = 3 \times 3.9 \\ 5 \times ED = 11.7 \\ ED = \frac{11.7}{5} \\ ED = 2.34$
