Answer: Option D
To find the answer, we can use the following formula:
Subtraction: a - b = c
Where,a = 3.87b = 2.59c = ?
Substituting the values in the formula, we get:
3.87 - 2.59 = 1.28
Therefore, the answer to the given question is 1.28.
Explanation:
Subtraction is one of the four basic arithmetic operations. It involves finding the difference between two numbers. In this case, we need to find the difference between 3.87 and 2.59.
To subtract two numbers, we can line up the decimal points and subtract the corresponding digits, starting from the rightmost column. If the digit in the second number is larger than the digit in the first number, we borrow one from the digit in the next column of the first number.
In this case, we can subtract 9 from 7, but we need to borrow one from the tens column. So, the 3 becomes 2 and the 8 becomes 18. Then, we can subtract 5 from 18, which gives us 13. Finally, we can subtract 2 from 3, which gives us 1.
Therefore, the answer is 1.28.
In summary, the answer to the given question is 1.28. Subtraction is a basic arithmetic operation that involves finding the difference between two numbers. To subtract two numbers, we can line up the decimal points and subtract the corresponding digits, starting from the rightmost column. If the digit in the second number is larger than the digit in the first number, we borrow one from the digit in the next column of the first number.
