Question

¿Qué par de números no tiene un producto igual a $36$ ?

Which pair of numbers does not have a product equal to $36?$

$\{-4, -9\}$

$\{-3, -12\}$

$\left\{\dfrac12, -72\right\}$

$\{1, 36\}$

$\left\{\dfrac32, 24\right\}$

Revisando cada par: $(-4)(-9) = 36,$ $(-3)(-12) = 36,$ $\dfrac12 \times (-72) = -36,$ $(1)(36) = 36,$ y $\dfrac32 \times 24 = 36.$

Solo $\dfrac12 \times (-72) = -36$ no es igual a $36.$

Por lo tanto, la respuesta correcta es C.

Checking each pair: $(-4)(-9) = 36,$ $(-3)(-12) = 36,$ $\dfrac12 \times (-72) = -36,$ $(1)(36) = 36,$ and $\dfrac32 \times 24 = 36.$

Only $\dfrac12 \times (-72) = -36$ fails to equal $36.$

Thus, the correct answer is C .
