Given that:
a / b = c / d
not (a = 0)
not (d = 0)
Prove that:
d / b = c / a
The following properties may be helpful:
- (a / b) ⋅ d = (d / b) ⋅ a
if a = b, then a ⋅ c = b ⋅ c
if not (c = 0), then (b / c) ⋅ c = b
if the following are true:
- a = b
- b = c
then a = c
if the following are true:
- a = b
- a = c
then b = c
if a = b, then a / c = b / c
if not (c = 0), then (b ⋅ c) / c = b
if the following are true:
- a = b
- a = c
then b = c
Please write your proof in the table below. Each row should contain one claim. The last claim is the statement that you are trying to prove.
