Hi!
Your answer would be: B-1
Reason being: Using P.E.M.D.A.S., we divide 42 (or, w) by 6, which equals 7.
now, 7 minus 6 equals 1.
__________________________________________________________
42/6-6
=7-6
=1
__________________________________________________________ Therefore, the answer is B/1.
Hope this helps!
Yours truly,
