1. Jawaban RizkybinMS
misal (.....) adalah x, maka:
1. 3/8 = x 5/56
3/8 = x + 5/56
3/8 - 5/56 = x
(21 - 5)/56 = x
16/56 = x
2/7 = x
2. 2/7 + x = 3/8
x = 3/8 - 2/7
x = (21 - 16)/56
x = 5/56
3. 5/9 = x 2/5
5/9 = x + 2/5
5/9 - 2/5 = x
(25-18)/45 = x
7/45 = x
4. 2/7 + x = 3/8
x = 3/8 - 2/7
x = (21 - 16)/56
x = 5/56
