Question

5/3d=15/9
please help!
soldve the equation. use the domain of rational numbers.

Answer 1

We can cross multiply to find:
\[
5\cdot9=15\cdot3d=45d=45
\]So:
\[
d=1
\]Another way would be:
\[
\frac{15}{9}=\frac{5\cdot\not3}{3\cdot\not3}=\frac{5}{3}
\]So, \(d\) would have to be one.

Answer 2
