Answer 2

Answer:

Remainder depends on value of quotient.

3 ( 9q + 7 ) = r

Step-by-step explanation:

Let, a = dividend

b = divisor

q = quotient

r = remainder

Then, a = bq + r

a = 36q + 21 - equation 1

a = 9q + r - equation 2

From equation 1 and 2,

36q + 21 = 9q + r

27q +21 = r

3 ( 9q + 7 ) = r
