Answer:

No they are not proportional.

Step-by-step explanation:

If you make the ratio into a fraction it looks like this

4/7 and 3/5

Now you cross multiply

4*5 and 3*7

Now you have 20 and 21

Those numbers are unequivelent

So they are not proportional

Multiplicative Inverse Property

Answer: Option C.

<u>Explanation:</u>

A multiplicative reverse is a reciprocal. A complementary is one of a couple of numbers that when increased with another number equivalents the number 1. The multiplicative converse property expresses that for each number that isn't zero, x increased with 1/x will rise to 1.

In mathematics, a multiplicative backwards or corresponding for a number x, meant by 1/x or x−1, is a number which when increased by x yields the multiplicative personality, 1. ... For instance, the corresponding of 5 is one fifth (1/5 or 0.2), and the equal of 0.25 is 1 partitioned by 0.25, or 4.
