Please help:

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:

14/n= 21

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.
