a. a/b=2/3
b/a=1/(a/b)=1/(2/3)=3/2
c. a/7b=(1/7)x(a/b)=(1/7)x2/3=2/21
d. 3a/11b=(3/11)x(a/b)=(3/11)x(2/3)=2/11
e. a/b=2/3, (a+b)/b=(2+3)/3=5/3
f, a/b=2/3, a/(a+b)=2/(3+2)=2/5
h. a/b=2/3, 3a/b=3x2/3, 3a/b=2/1, (3a-b)/b=(2-1)/1, (3a-b)/b=1
i. a/b=2/3, a/2b=2/6, a/2b=1/3, a/(a+2b)=1/(1+3), a/(a+2b)=1/4
