It says find the value of n.

This is a fraction. 3
- +n=1
4
what does n equal???

See previous post.

To find the value of n in the given fraction, you can follow these steps:

Step 1: Write down the fraction:
3
- + n = 1
4

Step 2: Simplify the fraction:
3/4 + n = 1

Step 3: Subtract 3/4 from both sides of the equation to isolate n:
n = 1 - 3/4

Step 4: Subtract the fractions on the right-hand side:
n = 4/4 - 3/4

Step 5: Simplify the fraction on the right-hand side:
n = 1/4

So, the value of n is 1/4.
