Question

If the product $AB$ equals 72, what are the missing entries $x,y,z$ in the table?

• A. $x=36,y=24,z=18$
• B. $x=24,y=36,z=18$
• C. $x=18,y=24,z=36$
• D. $x=18,y=36,z=24$

Answer 1

The correct option is A

$x=36,y=24,z=18$

72 can be written as a product in the following different ways:
$72=1\times 72$
$72=2\times 36$
$72=3\times 24$
$72=4\times 18$
$72=6\times 12$
$72=8\times 9$

Hence we can see that x = 36, y = 24 and z = 18
