Answer:

g. True

h. False

i. False

Step-by-step explanation:

g.


(1)/(14) is half of
(1)/(7)

This would be true because half of a number can be found by multiplying by
(1)/(2)

If you multiplied
(1)/(7) * (1)/(2)

The numerator is 1 * 1 which is 1

And then the denominator is 7 * 2 which is 14

That would give you
(1)/(14)

h.

The products of two reciprocals is 0

This is not true

Reason being, reciprocals are just the number flipped. If you times the number by itself, you don't get 0, you get 1.

Ex:
(2)/(8)

Its reciprocal is
(8)/(2)

So multiply them together


(2)/(8)* (8)/(2)

2 * 8 = 16

8 * 2 = 16


(16)/(16) = 1

i.

A whole number does not have a reciprocal

This is incorrect. If you think about it, a whole number is just the number, over 1

Ex:
(6)/(1)

This is still a whole number even though its written in fraction form because if you divide 6 by 1, your still going to get 6.

If you an write it as a fraction, it has a reciprocal.

The reciprocal in this case would be
(1)/(6)

I hope this helps, don't be afraid to reach out with any further questions!
