Show work! 99 points plus brainliest! if 6a=5b, what are the following ratios? a) a: b and b) b: a and c) 2a: 7b and d) \frac{a+b}{b} and e) \frac{a+b}{5a} and f) \frac{3a+3b}{a+b} and so !

A) 6a=5b so a=5/6*b a/b=5/6
b) 6a=5b so 6/5*a=b b/a=6/5
c) a/b=5/6 so (a/b)*(2/7)=2a/7b=(2/7)(5/6)=(5/21)
d) 6a=5b so b=6a/5 Thus (a+b)/b=(a+6a/5)/(6a/5)=(11a/5)/(6a/5)=11/6
e) 6a=5b so a=5b/6 Thus (a+b)/(5a)=(5b/6+b)/(5*5b/6)=(11b/6)/(25b/6)=11/25
f) (3a+3b)/(a+b)=3=3/1

Note, I wasn't quite sure what you meant by \frac

Ithink this answer would be c cause i seen this before
