Options

A. `0.27`
B. `0.3`
C. `0.327`
D. none of these

Answer

To solve the problem of subtracting \(0.68\) from \(1.007\), we will follow these steps:

### Step-by-Step Solution:

1. **Write the Problem**: We need to subtract \(0.68\) from \(1.007\). This can be written as:
\[ 1.007 - 0.68 \]

2. **Align the Numbers Vertically**: To make subtraction easier, we will align the numbers by their decimal points. We can add extra zeros to \(0.68\) to match the decimal places of \(1.007\). So, we rewrite \(0.68\) as \(0.680\):
\[ \begin{array}{r} 1.007 \\ - 0.680 \\ \hline \end{array} \]

3. **Perform the Subtraction**: Now we will subtract starting from the rightmost digit:
- In the thousandths place: \(7 - 0 = 7\)
- In the hundredths place: \(0 - 8\) (we need to borrow 1 from the tenths place, making it \(10 - 8 = 2\))
- In the tenths place: After borrowing, we have \(0 - 7\) (which is now \(0 - 7\) after borrowing, we need to borrow again making it \(10 - 7 = 3\))
- In the units place: \(1 - 0 = 1\)

Putting it all together:
\[ \begin{array}{r} 1.007 \\ - 0.680 \\ \hline 0.327 \\ \end{array} \]

4. **Final Answer**: The result of subtracting \(0.68\) from \(1.007\) is:
\[ 0.327 \]
