Tolong dong guys Buat jabarannya ya Nomor 15 sama 16

15) (525/100) x (24/7) = 18
       (75/10) : (27/8) = (75/10) x (8/27) = 20/9
       18 - 2/9 = 162/9 - 20/9 = 142/9  = 15 [tex] \frac{7}{9} [/tex]
    
      pecahan desimal
      (5,25) x (3,4) = 18
      (7,5) : (3,375) = 2,3
       18 - 2,3 = 15,7
      

16) (7/3) x (9/7) = 3
       3 : (36/10) = 3 x 10/36 = 30/36 = 5/6
       (5/6) + 4,375 = 5,2
