Number Patterns when counting by Tens
When you count by tens the numbers create a pattern. All the numbers end with a zero. The first digits are just like the numbers when you count (1, 2, 3, 4, 5, etc.). This pattern gives the numbers 10, 20, 30, 40, 50, etc.

The answer is 6.5 Explanation : 1. Find out the increase number by subtracting 4.58 - 4.30 = 0.28 or 6.51% 2. Divide the increase number 0.28 by 4.30 and multiple by 100 which gives you 6.51162791 . 3. Get rid of all the numbers behind 5 and you can’t round it because 1 is too small. Which then gives you the answer 6.5 :) <3
