Tolong Dong Plase :D
Penjumlahan tiga pecahan berturut-turut
1. 1 1/2 + 2/3 + 3/4 =
2.2 1/2 + 2 1/4 +3/5 =

Answer 1

1 1/2 + 2/3 + 3/4
= 3/2 + 2/3 + 3/4 (jadikan penyebutnya per 12)
= 18/12 + 8/12 + 9/12
= 35/12
= 2 11/12

2 1/2 + 2 1/4 + 3/5
= 5/2 + 9/4 + 3/5 (jadikan penyebutnya per 20)
= 50/20 + 45/20 + 12/20
= 107/20
= 5 7/20

Answer 2

1. 1/2 + 2/3 + 3/4 = 6/12 + 8/12+9/12 = 14/12 + 9/12 = 14/12 = 23/12 = 1 11/12
