True proportion means two ratios must be equal.
This means we should get 0 on solving
Let's check (you can use the calculator);
A. \(\frac{19}{15} - \frac{38}{25}\)
\(1.266 - 1.52 = -0.254\)
B. \(\frac{1.6}{2.5} - \frac{64}{100}\)
\(\frac{16}{25} - \frac{16}{25} = 0\)
C. \(\frac{4}{3} - \frac{10}{5}\)
\(1.33 - 2 = -0.667\)
D. \(\frac{14}{18} - \frac{18}{14}\)
\(\frac{7}{9} - \frac{9}{7}\)
\(0.777 - 1.285= -0.508 \)
E. \(\frac{3.6}{3} - \frac{18}{15}\)
\(1.2 - 1.2 = 0\)
Hence, B and E
