mohon jawabkanya.........

[tex] = 12 \frac{1}{2} + 5 \frac{3}{4} + 8 \frac{5}{6} \\ = \frac{25}{2} + \frac{23}{4} + \frac{53}{6} \\ = \frac{150}{12} + \frac{69}{12} + \frac{106}{12} \\ = \frac{325}{12} \\ = 27 \frac{1}{12} [/tex]

[tex]12 \frac{1}{2} + 5 \frac{3}{4} + 8 \frac{5}{6} = (12 + 5 + 8 = 25) \frac{1}{2} + \frac{3}{4} + \frac{5}{6} = \frac{6}{12} + \frac{9}{12} + \frac{10}{12} = \frac{25}{12} + 25 = 25 \frac{25}{12} + 27 \frac{1}{12} [/tex]
maaf klo salah
