Question

Solve the proportion-9/b=5/6

Answer 1

b = -10 4/5

Step-by-step explanation:

-9/b = 5/6

cross multiply:

`\begin{gathered} (-9)/(b)=(5)/(6) \\ -9(6)\text{ = 5(b)} \end{gathered}`
`\begin{gathered} -54\text{ = 5b} \\ \text{divied both sides by 5:} \\ -(54)/(5)=\frac{\text{ 5b}}{5} \\ -\frac{54}{5\text{ }}=\text{ b} \end{gathered}`

b = -54/5 = -10 4/5
