Ответ:
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
ANSWER: J= 3 1/7
Hope this helps! :)
