One way in which this question is trying to trip you up is that it gives the growth in two different forms. In the first day, Ben's bamboo plant grew 0.5 cm, while in the second day it grew another 8/10 cm.
Another way we can write 8/10 is 0.8 cm. You can double check this on your calculator.
So if we want the total growth of the bamboo plant, all we need to do is add the growth from each day
