Firstly, we must understand how decimals work. In decimal notation, each digit to the right of the decimal point represents a fraction of decreasing size. For example, the decimal 0.5 represents one-half or 50% of the whole, whereas the decimal 0.125 represents one-eighth or 12.5% of the whole.
We can start breaking down 120 by considering its place value system. The digit in the “tens” place, 2, represents 20. The digit in the “ones” place, 0, represents 0. To find the decimal equivalent of this number, we must convert each place value to a fraction of the whole.
To do this, we can use the following formula: Digit / Base Number^Place Value. In the case of 120, the base number is 10. Therefore, the tens digit, 2, can be represented as 2/10^1, which simplifies to 0.2. The ones digit, 0, can be represented as 0/10^0, which simplifies to 0.
We can also break down 120 by considering it as a sum of its component digits. 1+2+0 = 3. This smaller number, 3, gives us a clue that the decimal equivalent of 120 will be a slightly larger number. To find the decimal equivalent, we can add a decimal point to the right of the ones place and add zeroes until we reach the desired precision.
For example, if we want to find the decimal equivalent of 120 to two decimal places, we would write 120.00 and work from there. Using the formula above, the tens place becomes 2/10^1 = 0.2, the ones place becomes 0, and the hundredths place becomes 0/10^2 = 0.
In conclusion, breaking down the decimal answer to 120 helps us understand the number’s place value system and how each digit contributes to the overall value. By using fractions and converting each place value to a fraction of the whole, we can represent the decimal number in its true form.
