Mapel Math
Bab Pecahan

Diket :
■ 1,2
= 12/10
= 6/5

■ 80%
= 80/100
= 4/5

Penyelesaian :
2/5 + 1,2 - 80%
= 2/5 + 6/5 - 4/5
= 4/5
Opsi D

Semoga Membantu

Jb :

2/5 + 1,2 - 80%

= 2/5 + 12/10 - 80/100
= ( 2/5 + 12/10 ) - 80/100
= ( 4/10 + 12/10 ) - 80/100
= 16/10 - 80/100
= 160/100 - 80/100
= 80/100 → Sama² Dibagikan Dengan 20
= 4/5 ( D ) .


I Hope This Helps
