Question

What is the missing number.
5 / 6 = ?/18

Answer 1

15

Explanation:

So, we know that 5/6 is equal to something over 18. The denominator of 5/6 is a factor of 18, which makes it easy to find the missing numerator. 6 goes into 18 three times, so let's multiply 5 by 3. We get 15. 5/6=15/18, so your missing number is 15.
