Problem: 14 divided by a number is 21. What is the number?
my teacher says the answer is 2/3 but I don't get that answer.
I set it up:
Then tried solving as:
(n/14)(14/n) = 21/14
My answer = 1 1/2
What am I doing wrong? Thank you

14/x = 21
Multiply both sides by x.
14 = 21x
14/21 = x
2/3 = x
Let's see the proof:
14/(2/3) = 21
14 * (3/2) = 21
42/2 - 21
Yep! 2/3 is correct.
