Question

Wich equation has a solution of 2/3 for n?

Answer 1

`15n=10\\\\n=(10)/(15)\\\\n=(2)/(3)`

Explanation:

We need to find out of 4 options which equation has a solution of 2/3 for n.

Equation (1).

`n-1=(1)/(3)\\\\n=(1)/(3)+1\\\\n=(4)/(3)`

Equation (2).

`16n=24\\\\n=(24)/(16)\\\\n=(3)/(2)`

Equation (3).

`15n=10\\\\n=(10)/(15)\\\\n=(2)/(3)`

Equation (4).

`1(1)/(3)+n=3\\\\n=3-(4)/(3)\\\\n=(5)/(3)`

So, equation (3) has a value of n as 2/3. Hence, the correct option is (3).
