What number has the same value as 14 tens?
The correct answer and explanation is:
The number that has the same value as 14 tens is 140.
To explain, a “ten” refers to a unit of 10, so 14 tens means 14 groups of 10. When you multiply 14 by 10, you get 140. In other words: 14×10=14014 \times 10 = 140
Now, let’s break down the concept of place value in a number. In our base-10 system, the place value of each digit depends on its position in the number. The first position represents ones (1), the second position represents tens (10), the third position represents hundreds (100), and so on.
In the number 140:
- The digit 1 is in the hundreds place, so it represents 100.
- The digit 4 is in the tens place, so it represents 40 (which is 4 tens, or 4 × 10).
- The digit 0 is in the ones place, so it represents 0.
Adding these values together, you get: 100+40+0=140100 + 40 + 0 = 140
Therefore, 14 tens are equal to 140 because each “ten” is worth 10, and when you have 14 of them, you multiply 14 by 10, which results in 140.
This breakdown shows the importance of understanding place value, as it helps us easily calculate the value of numbers when they are broken down into groups like tens, hundreds, and so on.
