Question

2 to 4 and 11 to 11/2 are they proportional

Answer 1

Explanation:

In this case we must compare 2 to 4 and 11 to 11/2

1. The first ratio given is 2 to 4

$r_1=\frac{2}{4}=\frac{1}{2}$

So, the first ratio is 1/2

2. The second ratio given is 11 to 11/2

$\begin{gathered} r_2=\frac{11}{\frac{11}{2}}=\frac{2\cdot11}{11} \\ r_2=2 \end{gathered}$

Finally, since r1 ≠ r2 they are not proportional

ANSWER:

they are not proportional
