Answer:
40%
Explanation:
Step 1: Find the difference between the two numbers. 2.8 - 2 = 0.8
Step 2: Divide the difference by the original number. 0.8 / 2 = 0.4
Step 3: Multiply the result by 100 to get the percentage. 0.4 * 100 = 40 Therefore, the percent increase from 2 to 2.8 is 40%.
To further explain, if we start with 2 and it increases by 40%, it would result in a final value of 2 + 40% of 2 = 2.8. Another way to think about this is that the final value, 2.8, is 40% more than the original value, 2.
