Question

me pueden ayudar con explicacion porfavor se los ruego ​

Answer 1

Respuesta:

Pregunta 1

$\frac{84}{b} = \frac{32}{16} \\ \frac{84}{b} = \frac{2}{1} \\ 84 \times 1 = 2 \times b \\ \frac{84}{2} = b \\ 42 = b$

$\frac{4}{a} = \frac{32}{16} \\ \frac{4}{a} = \frac{2}{1} \\ 4 \times 1 = a \times 2 \\ \frac{4}{2} = a \\ 2 = a$

A × B = 2 × 42 = 84

Pregunta 2

$16 \times 3 = a \times 4 \\ 4 \times 3 = a \\ 12 = a$

$16 \times 3 = 8 \times b \\ 2 \times 3 = b \\ 6 = b$

A + B = 12 + 6 = 18
