1.1 5/8+3 2/12= 2.5 1/6+1 3/4= 3.3 1/3+5 2/7= 4.6 4/5+4 1/6= 5.7 2/3+2 7/8= 6.8 1/6+1 5/7= tolong dijawab pakai jalan

1. 1 5/8 + 3 2/12 = 13/8 + 38/12 = (disamakan penyebutnya dulu biar sama jadi 24 maka 13/8 * 3 dan 38/12 * 2) = 13/8 * 3 + 38/12 * 2 = 39/24 + 76/24 = 115/24 = 4 19/24

2. 5 1/6 + 1 3/4 = 31/6 + 7/4 = dijadikan 12 --> 31/6 * 2 + 7/4*3 = 68/12 + 21/12 = 89/12 = 7 5/12

3. 3 1/3 + 5 2/7 = 10/3 + 37/7 = penyebut dijadikan 21 --> 10/3 * 7 + 37/7 * 3 = 70/21 + 111/21 = 181/21 = 8 13/21

Pembahasan :
[tex] \frac{5}{8} +3 \ \frac{2}{12} = \frac{5}{8} + \frac{38}{12} = \frac{15}{24} + \frac{76}{24} = \frac{91}{24} \\ \frac{91}{24} = 3 \ \frac{19}{24} [/tex]
