Multiplication operation is used when asked to find one-tenth as large as another number
Solution:
Given that, We have to find what operation would we use when asked to find one – tenth as large as another number
In the given statement "one – tenth as large as another number " means a number is 1/10 times as large as another number" Here we have to use multiplication operation
Now, let another number be "a", and the resulting number be "b"
Then, "b" is one – tenth as large as "a"

So, here we used multiplication operation to find the result.
