Числитель:
2 3/8 : 3/4 + 24 7/9=
= 19/8 * 4/3 + 24 7/9=
= 19/6 + 24 7/9 =
=57/18 + 24 14/18 =
=3 3/18 + 24 14/18=
=27 17/18
Знаменатель:
7 1/8 - 157 4/5 : 24=
= 7,125 - 157,8:24=
= 7,125 - 6,575=
= 0,55 = 55/100= 11/20
Получилась дробь:
27 17/18 / (11/20) =
= 503/18 * 20/11=
= (503 * 10)/ (9*11) =
= 5030/99 = 50 80/99
