b)4/9=?/9
c)1/6=7/?
d)2/6=3/?
e)a/4=2a/?

Answer 1

a= 10
b= 4
c= 42
d= 9
e= 8

Answer 2

Resposta:

$a) \: \frac{3}{5} = \frac{6}{?} \\ \frac{3}{5} = \frac{6}{10} \\ \\ b) \: \frac{4}{9} = \frac{?}{9} \\ \frac{4}{9} = \frac{4}{9} \\ \\ c) \: \frac{1}{6} = \frac{7}{?} \\ \frac{1}{6} = \frac{7}{42} \\ \\ d) \: \frac{2}{6} = \frac{3}{?} \\ \frac{2}{6} = \frac{3}{9} \\ \\ e) \: \frac{a}{4} = \frac{2a}{?} \\ \\ \frac{a}{4} = \frac{2a}{8}$
