One number is 5 times another If the sum of their reciprocals is 2/15 find the two numbers Write a sentence that defines the variable you use and check your solution
n is one number
on it another number
n= 5*on
1/n + 1/on= 2/15
1/5on + 1/on= 2/15
multiply both sides by 5on
1 + 5= 10 on/15 solve for on, then n.
