Frank swims laps during swim practice. His coach tells him to swim a certain number of meters (total) each week. Here's a formula for this scenario:

n=t/p

t = total number of meters

p = length of a lap (in meters)

n = number of laps frank swims

Rewrite the formula to determine the length of a lap

N = t/p

t = total number of meters

p = length of a lap (in meters)

n = number of laps frank swims

Determine the length of a lap, p.

n = t/p

1) remove p as a denominator by multiplying both side w / p.

p*n = p (t/p)

pn = t

2) remove n by dividing both sides with n.

pn / n = t/n

*numerator n and denominator n cancels each other out.

p = t/n
