A the quotient of twenty-one times a number and eight
B the product of eight and twenty-one times a number
C the quotient of eight and twenty-one times a number
D the product of twenty-one times a number and eight

Answer 1

C

quotient-division
product-multiplication
(then the answer is multiplied by n not 8n)

Answer 2

Answer with explanation:

We have to describe the rational number in words

     $=\frac{8}{21 n}$

Dividend =8

Divisor =21 n

Quotient

     $=\frac{\text{Dividend}}{\text{Divisor}}\\\\=\frac{\text{Eight}}{\text{Twenty one} \times \text{A number}}$

Option C: → The quotient of eight and twenty-one times a number
