Express your answer as a mixed number.
W1fraction(N1, D1) + W2fraction(N2, D2) = {?}
=
\blue{W1} + \blue{fraction(N1, D1)} SIGN
\left(\pink{abs(W2)} + \pink{fraction(N2, D2)}\right)
=
\blue{W1} + \blue{fraction(N1, D1)} SIGN
\pink{abs(W2)} SIGN \pink{fraction(N2, D2)}
=
\blue{W1} SIGN \pink{abs(W2)} +
\blue{fraction(N1, D1)} SIGN \pink{fraction(N2, D2)}
=W1 + W2 + \blue{fraction(N1, D1)} SIGN \pink{fraction(N2, D2)}
= W1 + W2 + fraction(N1 + PM * N2, D2)
= W1 + W2 + fraction(N1 + PM * N2, D2)
