12 times 2 times 5 plus 2 gets rewritten as

A scientist measures the distance, in feet, between animals and the surface of a pond.
aleksandr82 [10.1K]

Considering the opposite of the rational number -1/2, the location of the snail is represented by the number 1/2.

<h3>What is the missing information?</h3>

This problem is incomplete, but researching it on a search engine, we have that:

  • The fish is located at -1/2 feet.
  • The snail is located at the opposite location of the fish.

<h3>What is the opposite of a rational number?</h3>

The opposite of a rational number a is given by -a, that is, it is the number with the opposite signal.

Hence, the <u>opposite of -1/2 is 1/2</u>, and the location of the snail is represented by the number 1/2.
