1. Which of the following are equivalent to -7 ?
$\frac{-49}{-7}$
$\frac{0}{-7}$
$\frac{49}{-7}$
$\frac{-21}{3}$
$\frac{21}{3}$
\(\boxed{\text{The options equivalent to -7 are } \frac{49}{-7} \text{ and } \frac{-21}{3}}\)
Step 1 :The question is asking for the equivalent of -7. To find the equivalent, we need to perform the operations given in each option and check if the result is -7.
Step 2 :Perform the operations for each option: \(\frac{-49}{-7}\), \(\frac{0}{-7}\), \(\frac{49}{-7}\), \(\frac{-21}{3}\), \(\frac{21}{3}\).
Step 3 :The options that result in -7 are \(\frac{49}{-7}\) and \(\frac{-21}{3}\).
Step 4 :\(\boxed{\text{The options equivalent to -7 are } \frac{49}{-7} \text{ and } \frac{-21}{3}}\)
