Kasrlarni birlikdan o‘tib ayirish

Noto'g'ri kasrni aralash kasrga o'tkazish:21/5 = 4 1/526/5 = 5 1/532/5 = 6 2/5 — detallar nomi bilan moslash (bolt, vint, mix, burama mix, shurup)

Amallar tartibi bilan hisoblash:(4 5/7 - 2 6/7) + 2 3/7, 9 1/3 - (6 1/3 - 1 2/3), (7 1/6 + 3 5/6) - 4 4/6 — qavslarni avval hisoblash

Amaliy masala (shesterna qutilari):12 - 4 3/4 = 7 1/4 → 7 1/4 - 2 2/4 = 4 3/4 → 4 3/4 - 1 3/4 = 3

Harfiy ifodalar: ishchilar soni a + (a - b) (a=70, b=20); detal soni m * n * 30 (m=1045, n=12)

Hisoblash mashqlari (11-topshiriq):(3 1/6 - 1 2/6) + 6 5/6, 7 4/9 - (6 1/9 - 3 2/9), 8 4/45 + (3 1/45 - 2 3/45)
