Question

. Suppose that A = D + E and that D/A = 0.75. Solve for D/E.

Answer 1

\[
\frac D A = \frac 3 4\\
A =\frac 4 3 D\\
\frac 4 3 D = D +E\\
\frac 4 3 \frac D E= \frac D E +1 \\


\]

Can you finish it?

Answer 2

\[
\frac D A = \frac 3 4\\
A =\frac 4 3 D\\
\frac 4 3 D = D +E\\
\frac 4 3 \frac D E-\frac D E=1 \\
\frac 1 3 \frac D E =1 \\
\frac D E=3
