1.95×10^6 - 1,845.19
1.95×10^6 - 1,845.19 = 1949554.81
To subtract 1,845.19 from 1.95×10^6, follow these steps:
Step 1: Rewrite the decimal number in scientific notation
1,845.19 = 1.84519 × 10^3
Step 2: Subtract the two numbers in scientific notation
1.95 × 10^6 - 1.84519 × 10^3
Step 3: To subtract the numbers, the exponents should be the same. Adjust the exponent of 1.84519 × 10^3 to match the exponent of 1.95 × 10^6.
1.84519 × 10^3 = 1.84519 × 10^(6-3) = 1.84519 × 10^3
Step 4: Perform the subtraction of the coefficients.
1.95 - 1.84519 = 0.10481
Step 5: Write the answer in scientific notation.
0.10481 × 10^6
The answer is approximately 0.10481 × 10^6.
To find the difference between 1.95×10^6 and 1,845.19, you can use decimal subtraction. Let me break down how you can do this:
1. Write down the two numbers one below the other, aligning the decimal points:
1.95×10^6
- 1,845.19
2. Since you are dealing with scientific notation in the first number (1.95×10^6), it is important to understand that the exponent represents how many places the decimal point needs to be moved to the right. In this case, the exponent 6 means that the decimal point should be moved six places to the right. So, rewrite the first number as:
1,950,000
- 1,845.19
3. Now you can perform the subtraction. Start from the rightmost column (ones place) and work your way to the left:
- Subtract the rightmost decimal digit: 0.19 - 0.19 = 0
- Subtract the next decimal digit: 0 - 1 = -1 (borrow 1 from the column to the left)
- Subtract the whole number digit: 5 - 4 - 1 (from the borrow) = 0
- Subtract the next whole number digit: 0 - 8 = -8 (borrow 1 from the column to the left)
- Continue subtracting the remaining digits: 5 - 1 - 1 (from the borrow) = 3 (carryover 1 from the column to the left)
- Subtract the leftmost whole number digit: 1 - 1 (from the carryover) = 0
4. Combine the results from each column:
1,950,000
- 1,845.19
______________
1,948,154.81
Therefore, the difference between 1.95×10^6 and 1,845.19 is approximately 1,948,154.81.
