Answer:
B) 45
Step-by-step explanation:
Divide all the numbers by 9 and see which number gets divided equally.
19 / 9 is 2 r 1 (r=remainder)
So A can't be the answer.
60 / 9 is 6 r 6
So C can't be the answer
79 / 9 is 8 r 7
So D can't be the answer
45 / 9 is 5, no remainders.
So B is the right answer
Hope this helps ;)
