106105 - 150 : x = 386
150 : x = 106105 - 386
150 : x = 105719
x = 150 : 105719
x = 150/105719
44820 : x = 83 . 5
44820 : x = 415
x = 44820 : 415
x = 108
106105 - 150 : x = 386
=> 150 : x = 105720
=> x = 5/3524
44820 : x = 83 x 5
=> 44820 : x = 415
=> x = 108
Tìm x :
106105 - 150 : x = 386
150 : x = 106105 - 386
150 : x = 105719
x = 150 : 105719
x = 150/105719
Vậy x = 150/105719
44820 : x = 83 × 5
44820 : x = 415
x = 44820 : 415
x = 108
Vậy x = 108
5 - X × 2/3 = 1/2
X × 2/3 = 5 - 1/2
X × 2/3 = 9/2
X = 9/2 : 2/3
X = 27/4
Vậy X = 27/4
106105 - 150 : x = 386
150 : x = 106105 - 386
150 : x = 105719
x = 150 : 105719
x = \(\frac{150}{105719}\)
44820 : x = 83 x 5
44820 : x = 415
x = 44820 : 415
x = 108
5 - \(x\)x \(\frac{2}{3}=\frac{1}{2}\)
\(x\times\frac{2}{3}\)\(=5-\frac{1}{2}\)
\(x\times\frac{2}{3}=\frac{9}{2}\)
\(x\) \(=\frac{9}{2}:\frac{2}{3}\)
\(x\) = \(\frac{27}{4}\)
\(44820:x=83.5\)
\(x=44820:83.5\)
\(x=2700\)
