1. a.2/3 + 4/5 + 5/6 = b.3/5 - 2/6 = 2. a.3/5 x 2/3 = b.4/5 : 2/3 = Yang bisa tolong jawab ya makasih :)

1. a) 2/3 + 4/5 + 5/6 = 20/30 + 24/30 + 25/30 = 69/30 = 2  9/30 = 2  3/10
    b) 3/5 - 2/6 = 18/30 - 10/30 = 8/30 = 4/15

2. a) 3/5 x 2/3 = 2/5
    b) 4/5 : 2/3 = 4/5 x 3/2 = 6/5 = 1  1/5

1. a. [tex] \frac{2}{3} + \frac{4}{5} + \frac{5}{6} = \frac{20}{30} + \frac{24}{30} + \frac{25}{30} = \frac{69}{30}=2 \frac{3}{10} [/tex]
    b. [tex] \frac{3}{5} - \frac{2}{6} = \frac{18}{30} - \frac{10}{30} = \frac{8}{30} = \frac{4}{15} [/tex]
2. a. [tex] \frac{3}{5} [/tex] x [tex] \frac{2}{3} = \frac{2}{5} [/tex]
    b. [tex] \frac{4}{5} [/tex] : [tex] \frac{2}{3} = 4/5 x 3/2 = 6/5
