J+1/2=3 9/14 show your work if possible . ty a) 1/7 b) 4 1/7 c) 1 5/9  d) 3 1/7

J + 1/2= 3 9/14
convert 3 9/14 to improper fraction

J + 1/2= [(3*14)+9]/14

J + 1/2= 51/14
subtract 1/2 from both sides

J= 51/14 - 1/2
change both to common denominators (of 14 in this case)

J= 51/14 - 7/14
subtract numerators only

J= 44/14
simplify numerator and denominator by 2

J= 22/7
convert back to mixed number

J= 3 1/7
