15-\lceil 7-\frac{8+1}{4}\rceil
8 hosil qilish uchun 2 va 4 ni ko'paytirish.
15-\lceil 7-\frac{9}{4}\rceil
9 olish uchun 8 va 1'ni qo'shing.
15-\lceil \frac{28}{4}-\frac{9}{4}\rceil
7 ni \frac{28}{4} kasrga o‘giring.
15-\lceil \frac{28-9}{4}\rceil
\frac{28}{4} va \frac{9}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.
15-\lceil \frac{19}{4}\rceil
19 olish uchun 28 dan 9 ni ayirish.
15-\lceil 4+\frac{3}{4}\rceil
19 ni 4 ga bo‘lganda, natija 4 va qoldiq 3 chiqadi. \frac{19}{4} ni 4+\frac{3}{4} sifatida qayta yozing.
