The difference between the big and small numbers is 8.01. If the larger decimal point is moved one place to the left, it is equal to the smaller decimal. What are the differences?
"A larger decimal point is equal to a smaller decimal point if it is moved one place to the left"
Then, the difference between the two numbers must be 9 times of the decimal (= 10 - 1)
Therefore, a small number is equal to:
= 8.01 ÷ (10 - 1)
= 0.89
The larger number is equal to:
= 0.89 × 10
= 8.9
