2 7/8+1 4/5= Dijawab ya kak

2 7/8 + 1 4/5 = 23/8 + 9/5 = 115/40 + 72/40 = 187/40 = 4 27/40

2 7/8 + 1 4/5

samakan penyebut pecahan itu dengan KPK
8 = 2^3
5 = 5
KPK = 2^3 × 5 = 40

2 .../40 + 1 .../40

2 .../40 = (40 ÷ 8) × 7
... = 5 × 7
... = 35

1 .../40 = (40 ÷ 5) × 4
... = 8 × 4
... = 32

2 35/40 + 1 32/40 = 3 67/40 = 4 27/40

jawabannya 4 27/40
