17-g

Answer 2

The answer is:
g-17

Whenever you come across a question that says "What is this number less than this other number," you always take the number that was said last, then place a subtraction sign after it, and then place the number that was said first after that subtraction sign. 

Another example would be:
What is 5 less than a number Y ?
First you must take the number mentioned last. That would be Y. Now, since the example question states "less than," you must put a subtraction sign after Y. Lastly, place the number that was said first after that subtraction sign. 

The answer to the example question would be: 
Y-5
