ini yaa, btw kalo ada pertanyaan lagi kamu bisa tanya lewat tele @autumnitee iyya !!

= 0,8 + 2/5 : ( 1½ - 0,75 ) × 1¼
= 8/10 + [ 2/5 : ( 3/2 - 75/100 ) × 5/4 ]
= 8/10 + [ 2/5 : ( 150/100 - 75/100 ) × 5/4 ]
= 8/10 + [ 2/5 : 25/100 × 5/4 ]
= 8/10 + [ 2/5 : 1/4 × 5/4 ]
= 8/10 + [ 2/5 × 4/1 × 5/4 ]
= 8/10 + 2/1
= 2 8/10
