Answer:
Now there are 9 ants.
Step-by-step explanation:
There are 4 ants on a log.
Then 5 ants crawl onto the log.
We are given that already there are 4 ants on a log and 5 more ants crawl onto the log.
So to calculate the total ants on the log now, we will add both the numbers.
4 + 5 = 9 ants
Now there are 9 ants on the log.
