Penjelasan dengan langkah-langkah:
1. 1/2 + 2,25 - 3/4 =
= 1/2 + 225/100 - 3/4
= 50/100 + 225/100 - 75/100
= 275/100 - 75/100
= 200/100
= 2
2. 75% - 0,25 + 2 1/4 =
= 75/100 - 25/100 + 9/4
= 50/100 + 225/100
= 275/100
= 11/4
= 2 3/4 (Pecahan Campuran)
3. 1 4/5 - (0,2 + 3/4 ) =
= 9/5 - (2/10 + 3/4)
= 9/5 - ( 4/20 + 15/20 )
= 9/5 - 14/20
= 36/30 - 14/20
= 22/20
= 11/10
= 1 1/10 (Pecahan Campuran)
