8 2/6 × 3 6/10 :12/15

8 2/6 = 50/6
          = 25/3

3 6/10 = 36/10
           = 18/5

12/15 = 4/5

25/3 × 18/5 ÷ 4/5 = 25/3 × 18/5 × 5/4
                            = 75/2
                            = 37 1/2

8 2/6=50/6
3 6/10=36/10
12/15(nanti diblk jk tnd diubah jd x)
50/6x36/10x12/15=37 1/2=75/2
Lbh mudah semua dicoret yg bisa dibagi, baginya atas bawah. Semoga bermanfaat
