Help! The options are: proportional , not proportional

storchak [24]

Answer: Not proportional

=======================================================

Explanation:

Let's assume the two fractions are equal.

If so, then,

$\frac{0.2}{2.6} = \frac{0.3}{3.6}\\\\0.2*3.6 = 2.6*0.3\\\\0.72 = 0.78$

The last equation is false, so the first equation is false.

Therefore, the two ratios are not proportional.

-------------

Another approach:

Calculate the decimal value of each fraction

$\frac{0.2}{2.6} \approx 0.07692\\\\\frac{0.3}{3.6} \approx 0.08333\\\\$

The two ratios result in different decimal values, so the two ratios are not equal, aka not proportional.
