What is 15% smaller than 620
The Correct Answer and Explanation is:
To calculate 15% smaller than 620, you first need to determine what 15% of 620 is, and then subtract that value from 620.
Step 1: Find 15% of 620.
To find 15% of 620, multiply 620 by 0.15 (since 15% is equivalent to 0.15 in decimal form):
[
620 \times 0.15 = 93
]
So, 15% of 620 is 93.
Step 2: Subtract 15% of 620 from 620.
Now, subtract 93 from 620 to get the number that is 15% smaller than 620:
[
620 – 93 = 527
]
Therefore, 15% smaller than 620 is 527.
Explanation:
Percentage calculations are widely used in real life, especially in financial contexts, discounts, statistics, and comparisons. When you are asked to find a value that is a certain percentage smaller than another, the process involves first calculating that percentage of the original number and then subtracting it from the original number.
In this case, 15% represents the fraction of the whole (620) that we are subtracting. By converting 15% to a decimal (0.15), we simplify the multiplication process. Multiplying 620 by 0.15 gives us the amount to subtract, which is 93. Finally, by subtracting 93 from 620, we find that the resulting value is 527.
This process can be applied to any scenario where you need to reduce a quantity by a certain percentage, whether you are calculating discounts, reductions in quantities, or comparing values. Understanding this concept is fundamental in fields like mathematics, finance, economics, and everyday decision-making. The ability to manipulate percentages allows for clearer insight into changes in values, whether they increase or decrease.
