Question 924501


let {{{a=1/2}}}, {{{b=1/4}}}, {{{c=1/6}}} and {{{d=1/8}}}
When you substitute and check what you get for the answer.

{{{ab+bc+cd =(1/2)(1/4)+(1/4)(1/6)+(1/6)(1/8)=3/16=highlight(3(1/16))}}}

now go to answer options and check which one will give you {{{highlight(3(1/16))}}}

start with option A:

{{{3ad=3(1/2)(1/8)=highlight(3(1/16))}}} ...so, option A is your answer
