0.75 dikali 1/9 ditambah 1/8 dikurangi 0.8 dikali 3/8

0,75 x 1/9 + 1/8 - 0,8 x 3/8 = 0,75 x 0,11 + 0,125 - 0,8 x 0,375
                                           = 0,0825 + 0,125 - 0,3
                                           = 0,2075 - 0,3
                                           = - 0,0925

Semoga Membantu :)
