A proportion is an equation where two ratios are equal and a proportion has given names and these are the extremes and the means. The extreme and the mean allows you to do cross multiplying. In the given proportion above 3/4 is the same with 3 : 4 and 15/20 is 15 : 20. The extremes are 3 and 20, whereas the means are 4 and 15. Therefore the correct answer would be the second option.

How to solve 3/5e-6=-2/5(e-10)-7

kaheart [24]

$\frac{3}{5} e-6=- \frac{2}{5}(e-10)-7$
$\frac{3}{5} e-6=- \frac{2}{5} e- \frac{2}{5}*(-10) -7 \\ \frac{3}{5} e-6=- \frac{2}{5} e+ \frac{20}{5} -7= \frac{3}{5} e-6=- \frac{2}{5} e+4 -7= \\$
$\frac{3}{5}e-6=- \frac{2}{5} e-3$ /*5
3e-18=-2e-15 /+15
3e-3=-2e /+2e
5e-3=0 /+3
5e=3
e= $\frac{3}{5}$
