Question

Multiplicative Inverse Property 2 · a = 1 use the property

Answer 1

Answer:

If you write a number as a fraction, that number's reciprocal is a fraction with the numerator and the denominator switched around. For example, the reciprocal of

4

5

is

5

4

. Some general rules to keep in mind:

-If the fraction has a

0

in the numerator, the reciprocal is undefined.

-If the fraction has a

0

in the denominator, the fraction itself is undefined. Thus it can't have a reciprocal.

-Any other fraction has exactly one reciprocal.

Finally, the reciprocal of a reciprocal is the original fraction. This means if you flip a fraction's numerator and denominator, and then flip them back, you get the number you started with.
