Q6: Fill in the blanks:
27 × 3000 = ______.
Ans: 27 × 3,000 = 27 × 3 × 1000 = 81 × 1000 = 81,000

Q7: Divide using the repeated subtraction method.
20 ÷ 4
Ans: 20 − 4 = 16
16 − 4 = 12
12 − 4 = 8
8 − 4 = 4
4 − 4 = 0
We have to subtract 4 from 20 five times, thus the quotient is 5.
Therefore,
20 ÷ 4 = 5

Q8: Divide using the repeated subtraction method.
20 ÷ 10

We have to subtract 10 from 20 two times, thus the quotient is 2 .
Therefore,
20 ÷ 10 = 2
