Bantu ya nomor 60,61,66 #JANGAN ASAL

60. 2:3 = 32:x
       2x = 3*32
       2x = 96
         x = 48
(60*40)-(48*32) = 2400-1536 = 864

61. 2:3 = 30:x
       2x = 3*30
       2x = 90
        x  = 45
(60*40)-(45*30) = 2400-1350 = 1050

66. 2:3 = 34:x
       2x = 3*34
       2x = 102
         x = 51
(60*40)-(51*34) = 2400-1734 = 666
