tenan pengurangan dari 3 5/6 - 1 1/4

3 5/6 → disederhanakan = 23/6
1 1/4 → disederhanakan = 5/4

23/6 - 5/4
= ( 23 x 2 / 6 x 2 ) - ( 5 x 3 / 4 x 3 )
= 46/12 - 15/12
= 31/12
= 2 7/12

semoga membantu

23/6 – 5/4
= 92 – 30/24
= 62/24 (sederhanakan -> dibagi 2)
= 31/12  -> Pecahan Biasa
= 2 7/12 -> Pecahan Campuran

Semoga Membantu!!!
