3 1/4+2 1/2+5/6 tolong yaaa pake cara

[tex]3 \frac{1}{4} = \frac{13}{4} \\ 2 \frac{1}{2} = \frac{5}{2} \\ [/tex]
maka cara menghitungnya :
[tex] = \frac{13}{4} + \frac{5}{2} + \frac{5}{6} \\ = \frac{(13 \times 3) + (5 \times 6) + (5 \times 2)}{12} \\ = \frac{39 + 30 + 10}{12} \\ = \frac{79}{12} \\ = 6 \frac{7}{12} [/tex]

maaf ya klo salah
semoga membantu
