What number has the same value has 30 tens
The Correct Answer and Explanation is:
The number that has the same value as 30 tens is 300.
Explanation
To understand why 30 tens is equal to 300, let’s break it down using basic place value and multiplication concepts.
In our number system, which is based on base ten, each digit in a number has a place value depending on its position (ones, tens, hundreds, etc.). One “ten” is equal to 10. So when we say “30 tens,” we are referring to 30 groups of 10.
This can be written as a multiplication problem: 30×10=30030 \times 10 = 300
So, 30 tens simply means you have 30 times 10, which equals 300.
Another way to visualize it is by counting in tens:
10, 20, 30, 40, 50, 60, 70, 80, 90, 100, … up to 300.
If you count 30 steps of 10, you’ll reach 300.
Let’s also relate this to place value. If you have a number with the digit 3 in the “hundreds” place, it means: 3×100=3003 \times 100 = 300
But if you break 300 into tens: 300÷10=30300 \div 10 = 30
This confirms that there are 30 tens in 300.
We can also consider money as an example. If you have 30 ten-dollar bills, how much money do you have? 30×10=300 dollars30 \times 10 = 300 \text{ dollars}
This real-life application shows how multiplication and place value help us understand quantities.
In summary, the number that has the same value as 30 tens is 300, because:
- Each “ten” equals 10
- 30 tens = 30 × 10 = 300
- It fits place value logic and real-life examples
Understanding how to group and multiply numbers using place value helps you interpret such phrases correctly in both math and everyday life.
