Question

Como se chega a esse resultado ?


$x = 12 . \frac{30}{20}.\frac{2}{1}.\frac{8}{12} = 24$

Answer 1

$x = 12 . \frac{30}{20}.\frac{2}{1}.\frac{8}{12} = 24$

x= 12 .(30/20) .2/1 .(8/12)

x=12.(30÷10/20÷10).(2).(8/12)=

x=12.(3/2).(2).(8/12)

x=(12.3)/2. (2.8/12)

x=6.3.(16/12)

x=18.(16/12)

x=18.(16÷4/12÷4)

x=18.(4/3)

x=4.(18)/3

X=4.(6)

x=24
