Tolong jawab y kk.. Please besok di kumpulin

1. 6 5/8 + 3 3/4 - 4 2/3 = 6+3+5 ( 5/8+3/4-2/4)
= 13 ( 5+6-4/8)
= 13 ( 7/4)
= 13 7/4


2. 2 1/4 : 1 1/4 × 1 3/4 = 9/4 : 5/4 × 7/4
= 2,25 : 1,25 × 1,75
= 1,80 × 1,75
= 3,15
= 3 15/100
= 15/100 : 5 = 3/20
= 3 3/20

3. 13 1/2 : 0,5 × 24/27 - 12 = 13 : 0,5 × 0,88 - 12
= 26 × 0,88
= 22,88 - 12
= 10,88
= 10 88/100
= 88/100 : 2
= 22/50 : 2
= 11/25
= 10 11/25



MAAF KALAU SALAH...ITU JAWABAN MENURUT SAYA....
