Question

1. Hasil dari 1/5+2 3/4= 2. Hasil dari 4/5+3/4+7/10. 3. Hasil dari 1/3+4/5+5/6. 4. 3,24+4,02+0,12. Beserta caranya ya, terima kasih ^_^

Answer 1

1) 1/5+(2.3/4) = 1/5 + 3/2 = 2/10 + 15/10 = 17/10 = 1,7
2) 4/5+3/4+7/10 = 16/20 + 15/20+ 14/20 = 45/20 = 2,25
3) 1/3 + 4/5 + 5/6 = 10/30 + 24/30 + 25/30 = 59/30 =1,96 
4)3,24+4,20+0,12 = Disamakan penyebutnya dulu baru dijumlah. Hasilnya 7,38

Answer 2

1.    1/5 + 2 3/4 = 1/5 + 11/4 = 4/20 + 55/20 = 59/20 = 2  19/20
2. 4/5 + 3/4 + 7/10 = 16/20 + 15/20 + 14/20 = 45/20 = 4  1/4
3. 1/3 + 4/5 + 5/6 = 10/30 + 24/30 + 25/30 = 59/30 = 1  29/30
4. 3,24 +4,02 + 0,12 = 7,38
