First to answer

Answer:

The answer is True:

Let's solve your equation step-by-step.

1/n−1 = 4/15

Step 1: Cross-multiply.

1/n−1 = 41/ 5

(1)*(15)=4*(n−1)

15=4n−4

Step 2: Flip the equation.

4n−4=15

Step 3: Add 4 to both sides.

4n−4+4=15+4

4n=19

Step 4: Divide both sides by 4.

4n/4=19/4

n=19/4

simplify:

19/4 = 4.75

4.75 in decimal for is equal to 4 3/4
