ANSWER

5 numbers they have in common

Step-by-step explanation

Set A has all whole numbers to 20:


A\colon1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20

Set B has only odd integer between 8 and 18:


B\colon9,11,13,15,17

We can see that set B is inside set A, because it has whole numbers that are less than 20, so the amount of numbers they have in common is all of set B: 5 numbers.
