When we say something is ten times less than 100, it means we are looking for a number that is one-tenth of 100. Finding something ten times less than 100 requires dividing 100 by 10, which gives us 10. Therefore, 10 is ten times less than 100.
How?
To get a better understanding of the concept, let’s break it down. The phrase « ten times less than » is often confused with « ten times smaller than, » but they mean entirely different things. To show the difference, let’s look at an example:
If x is ten times smaller than y, then x is 1/10th of y (or 0.1y).
If x is ten times less than y, then x is 1/10th of what y was (or 0.9y).
Therefore, when we say something is ten times less than 100, we mean that it is 1/10th of what 100 was, which results in 10.
Why?
Understanding what ten times less than means can help us create clear and concise communication. If we’re not careful, we might use the phrase « ten times less than » interchangeably with « ten times smaller than, » leading to confusion and misunderstandings.
Moreover, knowing the concept of ten times less than can help us make better sense of percentages and ratios, which often use multiplication and division. For instance, if your energy bill this month was ten times less than last month, it would be 1/10th of what you paid last month, or 90% less.
Who?
Anyone who works with numbers, whether in science, finance, or engineering, is likely to encounter situations where they need to determine what is ten times less than a given value. Being familiar with the concept can help avoid misunderstanding and improve accuracy in calculations.
Examples
Apart from the example of finding something ten times less than 100, here are eight other questions that involve the concept of « ten times less than » and their respective answers:
1. What is ten times less than 1000?
Answer: Dividing 1000 by 10 gives us 100. Therefore, 100 is ten times less than 1000.
2. What is ten times less than 50?
Answer: Dividing 50 by 10 gives us 5. Therefore, 5 is ten times less than 50.
3. If a recipe calls for ten times less salt than flour, and we use 2 cups of flour, how much salt should we use?
Answer: If we use ten times less salt than the amount of flour, we need to divide the amount of flour by ten. So, 2 cups of flour divided by ten gives us 0.2 cups of salt.
4. What is ten times less than one million?
Answer: Dividing one million by 10 gives us 100,000. Therefore, 100,000 is ten times less than one million.
5. What is ten times less than 7?
Answer: Dividing 7 by 10 gives us 0.7. Therefore, 0.7 is ten times less than 7.
6. If John’s test score was ten times less than Mary’s score, and Mary scored 90%, what was John’s score?
Answer: To find John’s score, we need to determine what 90% was ten times less than. If Mary scored 90%, and that’s ten times more than John’s score, then John’s score would be 9% (that’s one-tenth of 90%).
7. What is ten times less than 2000?
Answer: Dividing 2000 by 10 gives us 200. Therefore, 200 is ten times less than 2000.
8. If you reduce something ten times less than its original size, what percentage would it be?
Answer: If you reduce something ten times less than its original size, you’re actually left with one-tenth of the original size. Therefore, the final size would be 10% of the original size.
