\begin{array}{ll} \text{Column A} & \text{Column B} \\ \frac{15\times 21\times 14}{3\times 7\times 5} & \frac{48\times 81\times 63}{12\times 9\times 9} \end{array}

Solution:

Concept:

Simplify each column by cancelling common factors, then compare the values.

Explanation:

Column A:

\frac{15\times 21\times 14}{3\times 7\times 5}

Cancel

15

with

3\times5

, and

21

with

7

=14\times3=42

Column B:

\frac{48\times81\times63}{12\times9\times9}

Cancel

48

with

12

81

with

9

, and

63

with

9

=4\times9\times7=252

Since

252>42

, Column B is greater.

Answer:
