24

Step-by-step explanation:

if 2 of her gerbils have 2 babies every 2 months there will be 24 by the end of one year

2x (1x12) = 24

They will have 24 babies in one year

Step-by-step explanation:

All you need to do is add 6 babies every two months starting in January. Include January as the gerbils having their first 6 babies. Every 2 months includes 4 months out of the year. 6*4 = 24 babies.
