Cho 2 số a,b biết rằng: \({a \over b} = {2 \over 3};BC(a,b) = 12 \). Tìm 2 số a,b.
A.\(\left( {a;b} \right) \in \left\{ {\left( {3} \right),\left( {6} \right)} \right\}\)
B.\(\left( {a;b} \right) \in \left\{ {\left( {-3;3} \right),\left( {- 6;6} \right)} \right\}\)
C.\(\left( {a;b} \right) \in \left\{ {\left( {2;3} \right),\left( {4;6} \right)} \right\}\)
D.\(\left( {a;b} \right) \in \left\{ {\left( {2;3} \right),\left( {6} \right)} \right\}\)
A.\(\left( {a;b} \right) \in \left\{ {\left( {3} \right),\left( {6} \right)} \right\}\)
B.\(\left( {a;b} \right) \in \left\{ {\left( {-3;3} \right),\left( {- 6;6} \right)} \right\}\)
C.\(\left( {a;b} \right) \in \left\{ {\left( {2;3} \right),\left( {4;6} \right)} \right\}\)
D.\(\left( {a;b} \right) \in \left\{ {\left( {2;3} \right),\left( {6} \right)} \right\}\)
