Answer:
There would be 40 ones in the given number.
Step-by-step explanation:
We are asked to find the number of ones in \(10\times 4\text{ ones}\).
Upon expanding our given number, we will get:
\(10\times 4\text{ ones}=40\text{ ones}\)
Therefore, there are 40 ones in our given number \(10\times 4\text{ ones}\).
