hasil dari 3/8+21/4-75%

3/8 + 21/4 - 75%
=> 3/8 + 21/4 - 75/100
=> 75/200 + 1050/200 - 150/200
=> 975/200
=> 195/40
=> 39/8
=> 4 7/8

semoga membantu

3/8 + 21/4 - 75 %
= 3/8 + 21/4 - 75/100
= 75/200 + 1050/200 - 150/200
= 1125/200 - 150/200
= 975/200 = 39/8 = 4 7/8
Jadi, hasilnya 4 7/8
# 200 didapat dari KPK 8, 4, dan 100.
