12/45 + 5 7/30 Tolong jawab yaaa Yg 5 7/30 pecahan campuran Yg 12/45 pecahan biasa

[tex] \frac{12}{45} + 5 \frac{7}{30} \\ = \frac{12}{45} + \frac{157}{30} \\ = \frac{24 + 471}{90} \\ = \frac{495}{90} \div 45 \\ = \frac{11}{2} [/tex]

12/45 + 157/30 = 24/90 + 471/90 = 495/90 = 5 1/2 = 5,5
Semoga membantu :-)
