Answer 1

Answer:

no

Step-by-step explanation:

because 8× 5= 40 and 12× 5 = 60

but they have given 61 , so they are not in proportion

Answer 2

Answer:

No, they are not in proportion

Step-by-step explanation:

$\frac{12}{8} = \frac{3}{2}$

$\frac{61}{40}$

$\frac{3}{2} \: not \: equal \: to \: \frac{61}{40}$

$thus \: they \: are \: not \: in \: proportion$
