First one: so you write 7:6
and underneath write 52:58 then cross multiply. so does 52 multiply 6 divided 7 give 58? No, so they do not form a proportion.
Well I think I also know the second one. Basically you write them as follows:
34:23
X: 46 Then you cross multiply, so it's (46 multiply 34) Divided by 23 =68

1. 13/14 so, No, it does not.
2. x=68
Check: 68/46=34/23=34/23
