My try for this solution:

Since its asking for the current through the diode only and it is silicon:

Id1 = .7v/200 ohms
= .0035 A

i was thinking of the Idi as 50-.7/ 200 ohms = .2465. but that would be for the resistor right?

Just trying to confirm

Thx

The second answer of 0.2465A is OK. Not sure where you were going with the first idea - definitely not correct.

then what would the current be across the resistor

It's a simple series circuit - What do you know about the current in each component of a series circuit?
