Required answer:

Question:
Use cross products to identify the equation needed to solve this proportion:
5/x = 2/9
0 5x = 18
0 2x = 45
O 9x = 10
O 2x = 14
Equation Given:
5/x = 2/9
Step by step explanation:

equation formed

we have taken 9 up to multiply it with 5 and x up to multiply it with2

after multiplication we get 45 = 2x
extra steps:

transferring 2 to other side to divide it with 45

so finally we get 22.5
