If 3n=5, then 1=
a)5/3
b)3n/5
c)0.6
d)none of the above

the answer is b) 3N/5

Step-by-step explanation:

The questions says that 3N = 5.

For obtain the answer, we need that one side of the equation becomes equal to 1.

the way to achieve that situation is to divide by 3N or by 5 all the equation:

Case 1. Divide by 3N

If divide all the terms in the initial equation by 3N, it gets:

3N=5

However this solutions is not in the multiple choice answers.

Case 2. Divide by 5

If divide all the terms in the initial equation by 3N, it gets:

3N=5

It also can be writing as

Then, the correct answer is 1 = 3N/5

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
