3.98 Million - 1 7/8 Million =
Understanding the Problem
When dealing with large numbers and fractions, it's essential to approach the problem systematically. In this case, we're required to subtract 1 7/8 million from 3.98 million. To begin, let's break down the fraction 1 7/8 into a decimal. The fraction 7/8 can be converted to a decimal by dividing the numerator by the denominator: 7 ÷ 8 = 0.875. Therefore, 1 7/8 is equivalent to 1.875.
Converting Mixed Numbers to Decimals
To make the calculation easier, let's convert the mixed number 1 7/8 into a decimal. As mentioned earlier, 1 7/8 is equivalent to 1.875. Now, we can rewrite the problem as 3.98 million - 1.875 million.
Subtracting Large Numbers
When subtracting large numbers, it's crucial to line up the decimal points and subtract the corresponding digits. In this case, we have:
3.98 million
- 1.875 million
To perform the subtraction, we'll start by subtracting the digits in the millionths place. Since 8 is greater than 5, we'll borrow 1 from the hundredths place, making it 0.98 - 0.875 = 0.105. Now, we can subtract the digits in the hundredths place: 0.98 - 0.875 = 0.105.
Performing the Subtraction
Now that we've lined up the decimal points and subtracted the corresponding digits, we can perform the subtraction:
3.98 million
- 1.875 million
Subtracting the digits in the millionths place, we get:
3.98 - 1.875 = 2.105
Rounding the Answer
Since we're dealing with large numbers, it's essential to consider rounding the answer. However, in this case, the answer is already in a precise format, so we don't need to round it.
Conclusion
In conclusion, when subtracting 1 7/8 million from 3.98 million, we get 2.105 million. This answer is precise and accurate, and it's essential to consider rounding the answer when dealing with large numbers.
