1.hasil dari 7 1/8 + 2 1/2 2.hasil dari 2 2/5 x 0,5

1. 7 1/8 + 2 1/2
    7+2 ( 1/8 + 1/2)
    9 ( 2/16 + 8/16)
    9 (10 / 16)
    9 5/8

2. 2 2/5 = 12/5
    0,5 = 1/2
    12/5 x 1/2 = 12/10 = 1 2/10 = 1 1/5
              atau
     2.4 x 0.5 = 1.2

1. 7 1/8 + 2 1/2 = 55/8 + 5/2 = 55/8 + 20/8 = 75/8

2. 2 2/5 * 0,5 = 12/5 *5/10 = 60/50
