– 7 0 we divide.
2 1 0
– 2 1 0

So, 126 people can sit in each row.
Working
Example 28: A bakery can bake 2,820 buns in 12 days. How
many buns can it bake in 26 days? 2 3 5 1
12 2 8 2 0 2 3
Solution: Number of buns baked in 12 days = 2,820 – 2 4 ↓ 2 3 5

Number of buns baked in 1 day = 2,820 ÷ 12 4 2 × 2 6
= 235 – 3 6 1
6 0
Number of buns baked in 26 days = 235 × 26 – 6 0 1 4 1 0
= 6,110 0 + 4 7 0 0
6 1 1 0
So, 6,110 buns can be baked in 26 days.
