Question

Choose the correct value of A, B, C and D which are missing in the following table

Repeated Subtraction of 21 $÷$ 7

Steps	Dividend	Divisor	Operation
1	21	A	21 - 7 = B
2	C	7	14 - 7 = 7
3	7	7	7 - 7 = D

• A. A = 7, B = 14, C = 14, D = 0
• B. A = 21, B = 0, C = 7, D = 0
• C. A = 7, B = 10, C = 21, D = 0
• D. A = 7, B = 14, C = 21, D = 0

Answer 1

The correct option is A A = 7, B = 14, C = 14, D = 0

As division is repeated subtraction, so solving 21 $÷$ 7 by repeated subtraction method
