I am preparing for Chemistry, can anyone explain how to do this problem?

Question

a=3

b=12

c=-5

d=-15

e=4

c/ba divided by d/ae + a/c

Answer 1

What do you mean, this is a simple "plug in number" problem. Just plug the numbers into the equation and solve.

Answer 2

...is this a trick question

why not use the calculator

Answer 3

c/ba divided by d/ae + a/c

with a division dividing another division one of the divisions is flipped so instead of divided by d/ae it is multiply ae/d. then it should be simple enough to work out
