leo knows that each time a digit moves one place to the left in a whole number the value of the digit is 10 times as much. descr
Serga [27]

Answer:

Leo is true for any numbers (including decimal numbers)

Step-by-step explanation:

* Lets explain how to solve the problem

- In number 256

# 6 is the unit digit (one digit)

# 5 is the ten digit (10 digit)

# 2 is the hundred digit (100 digit)

- If we change the number to 2563

# 6 digit is moved 1 place to the left now its place changed from unit

  digit to ten digit (from 1 to 10) that means 6 in the second number

  is 10 times the 6 in the first number

# 5 digit is moved 1 place to the left now its place changed from ten

  digit to hundred digit (from 10 to 100) that means 5 in the second

  number is 10 times the 5 in the first number

# 2 digit is moved 1 place to the left now its place changed from  

  hundred digit to thousand digit (from 100 to 1000) that means 2

  in the second number is 10 times the 2 in the first number

- In number 2.345

# 2 is the unit digit (one digit)

# 3 is the tenth digit (1/10 digit)

# 4 is the hundredth digit (1/100 digit)

# 5 is the thousandth digit (1/1000 digit)

- If we change the number to 23.45

# 3 digit is moved 1 place to the left now its place changed from tenth

  digit to unit digit (from 1/10 to 1) that means 3 in the second number

  is 10 times the 3 in the first number

# 4 digit is moved 1 place to the left now its place changed from  

  hundredth digit to tenth digit (from 1/100 to 1/10) that means 4 in the

  second number is 10 times the 5 in the first number

# 5 digit is moved 1 place to the left now its place changed from  

  thousandth digit to hundredth digit (from 1/1000 to 1/100) that means

  5 in the second number is 10 times the 5 in the first number

∴ Leo is true for any numbers (including decimal numbers)
