Answer 6

can u show how u got that --"

Answer 7

I followed what you wrote.
DX/AX = DN/AK
2.3/(6+2.2) = DN/4.9
I solved what was in the () which equaled 5.06
then cross multiplied

Answer 8

okay, let me try and verify this
2.3/(6+2.2) = DN/4.9
2.3/8.2 = DN/4.9
8.2 DN = 2.3 * 4.9
8.2 DN = 11.27
DN = 11.27/8.2
DN = 1.374

Answer 9

That makes more sense. I added 6 + 2.2 wrong. thanks

Answer 10

no problem :)
