Question

Is 3/4 proportional to 15/18

Answer 1

We have that ratios are proportional if they represent the same relationship. Then, in this case, we have the following expressions:

`\begin{gathered} (3)/(4)=(15)/(18) \\ \Rightarrow3\cdot18=4\cdot15 \\ \Rightarrow54=60 \end{gathered}`

we have that 54 = 60, which is never true, therefore, 3/4 is not proportional to 15/18
