Jika A =2/3 kelereng B ,dan B 4/5 kelereng C jika kelereng mereka 105 butir tentukan jumlah kelereng masing-masing

A = 2/3 B

B = 4/5 C; C = 5/4 B

A + B + C = 105

2/3 B + B + 5/4 B = 105

8/12 B + 12/12 B + 15/12 B =105

35/12 B =105

B = 105.12*35

B = 3.12 = 36

A = 2/3*36

A = 24

C = 5/4*36

C = 45

A = 27 Kelereng, B = 36 Kelereng, C = 45 Kelereng
