Q: How do we know it's 10 times greater?
A: Multiply!
You multiply 40×10 and get 400! To see if the answer is right divide 400÷40 and get 10. Or divide 400÷10 and get 40.
Basically, when you're multiplying something by 10 you just add a 0. When you divide by 10 you remove a 0.
That's how the number 4 in 5,401 is 10 times greater than the number 4 in 3,642.
