tolong dijawab,besok di kumpulkan.....

[tex] \frac{3}{4} + 5.2 + 12 \frac{1}{2} \% \\ = \frac{3}{4} + \frac{52}{10} + \frac{25}{200} \\ = \frac{150 + 104 + 25}{200} \\ = \frac{279}{200} = 1.395[/tex]
hasil akhir 1,395... -->> koma bukan ribuan

3/4 + 5.2 + 12 1/2%
3/4 + 52/100 + 25/200
150/200 + 104/200 + 25/200
154/200+ 25/200 = 179/200
Semoga Membantu
