How do you solve #n/(n+1)=3/5#?
Firstly we can multiply both sides by
Now we can multiply both sides by
First, you have to understand cross multiplying.
5 would cross with n to make 5n
3 would cross with n + 1 to make 3n + 3
The equation would look like 5n =
Bring 3n over to 5n and subtract from both sides.
3n - 3n would cancel out while 5n - 3n would give 2n.
The equation would look like: 2n = 3
