1 1/4+2 3/5+....=5 1/3

[tex] 1 \frac{1}{4} + 2 \frac{3}{5} + x = 5 \frac{1}{3} [/tex]
Maka, nilai x yang memenuhi adalah :
[tex]x = 5 \frac{1}{3} - 1 \frac{1}{4} - 2 \frac{2}{3} \\ x = \frac{16}{3} - \frac{5}{4} - \frac{8}{3} \\ x = \frac{64}{12} - \frac{15}{12} - \frac{32}{12} \\x = \frac{64 - 15 - 32}{12} \\ x = \frac{20}{12} \\ x = \frac{5}{3} \\ x = 1 \frac{2}{3} [/tex]
