( 1 x X ) x 12 = 25
1 x X=25:12
1 x X=\(\dfrac{25}{12}\)
X=\(\dfrac{25}{12}\):1
X=\(\dfrac{25}{12}\)
`( 1 xx x) xx 12 = 25`
` 1 xx x = 25 : 12`
` 1 xx x = 25/12`
` x = 25/12 : 1`
` x = 25/12`
Vậy ` x = 25/12`
\(\left(1.X\right).12=25\)
\(1.X=25:12\)
\(1.X=\dfrac{25}{12}\)
\(X=\dfrac{25}{12}:1\)
\(X=\dfrac{25}{12}\)
