Assuming Ken gets the same percentage as usuall in these 5 times, we can calculated how many times he did get on base by calculating 60% of 5.
To do this we transform 60% into decimal my dropping the percentage sign and dividing it by 100 and then we multiply the decimal by 5:
![(60)/(100)\cdot5=0.6\cdot5=3](https://img.qammunity.org/2023/formulas/mathematics/college/l0tpmkziuxssexnlofoxwbq4ra99eiy8h2.png)
So, Ken got on base 3 times.
