operasi penjumlahan 3 pecahan..no 1).4/5+3/6+5/10= no 2).7/8+5/6+3/4= no 3).4/6+7/10+3/12= no 4).2/6+3/8+8/12= no 5).3/5+2/10+5/6=

[tex]1. \frac{24}{30} + \frac{15}{30} + \frac{15}{30} = \frac{54}{30} \\ 2. \frac{21}{24} + \frac{20}{24} + \frac{18}{24} = \frac{59}{24} \\ 3. \frac{40}{60} + \frac{42}{60} + \frac{15}{60} = \frac{97}{60} \\ 4. \frac{8}{24} + \frac{9}{24} + \frac{16}{24} = \frac{33}{24} \\ 5. \frac{18}{30} + \frac{6}{30} + \frac{25}{30} = \frac{49}{30} \\ 6. \frac{21}{56} + \frac{40}{56} + \frac{28}{56} = \frac{99}{56} [/tex]
semoga membantu, mohon maaf jika salah :)
