Question

Do the following ratios have a proportional relationship? Determine proportionality by using cross multiplication

Answer 1

So, we will use cross multiplication​ to show if the ratios have a proportional relationship

`\begin{gathered} (8)/(12)\text{and }(5)/(7) \\ \end{gathered}`

12 * 5 = 60

8 * 7 = 56

so, the the rations doesn't have a proportional relationship

b) 24 : 16 and 9 : 6

Write the ratios as fractions

`(24)/(16)and(9)/(6)`

So, 24 * 6 = 144

And 16 * 9 = 144

so, the ratios have a proportional relationship
