Математика: 97/2-7 7/16 9 7/24 разделить на 7 7/16 вычилите

mamrykovaksun · Answer

9_7/2 - 7_7/16 = 25/2 - 106/16 = (25*8-106)/16 = (200-106)/16 = 94/16 = 47/8
47/8 = 5_7/8 = 5 целых и 7/8
(9_7/24):(7_7/16) = (223/24):(119/16) = (223/24)*(16/119) = (223*2)/(119*3) =
= 446/357
446/357 = 1_89/357 = 1 целая и 89/357
