In a proportion, we use the Cross Product Property (Cross Multiplication).
Therefore,
In 5/2=2/x, we will multiply diagonally:
So 5 times X is 5X, and 2 times 2 is 4.
Now, we have an equation: 5X=4, where we divide 5 from both sides to isolate X:
5X/5=4/5.
Therefore, X=4/5 or 0.8 will be your answer.
