8 kg 70g - 0.526 kg is equal to

Options

A. 7.544kg
B. 7.455 kg
C. 8 kg
D. 75.44g

Answer

To solve the problem \( 8 \text{ kg } 70 \text{ g} - 0.526 \text{ kg} \), we will follow these steps:

### Step 1: Convert 8 kg 70 g to kilograms
First, we need to convert 70 grams into kilograms. We know that:
\[ 1 \text{ kg} = 1000 \text{ g} \]
So, to convert grams to kilograms, we use the formula:
\[ \text{kg} = \frac{\text{g}}{1000} \]
Thus, for 70 grams:
\[ 70 \text{ g} = \frac{70}{1000} \text{ kg} = 0.070 \text{ kg} \]

### Step 2: Add the kilograms
Now, we can express \( 8 \text{ kg } 70 \text{ g} \) as:
\[ 8 \text{ kg } + 0.070 \text{ kg} = 8.070 \text{ kg} \]

### Step 3: Perform the subtraction
Now we need to subtract \( 0.526 \text{ kg} \) from \( 8.070 \text{ kg} \):
\[ 8.070 \text{ kg} - 0.526 \text{ kg} \]

### Step 4: Align the numbers for subtraction
Align the numbers vertically:
```
8.070
- 0.526
```

### Step 5: Subtract the numbers
Now, we subtract column by column:
- Starting from the rightmost column:
- \( 0 - 6 \) cannot be done, so we borrow 1 from the next column (which is 7, making it 6):
- \( 10 - 6 = 4 \)

- Next column:
- \( 6 - 2 = 4 \)

- Next column:
- \( 8 - 0 = 8 \)

So, we have:
\[ 8.070 - 0.526 = 7.544 \text{ kg} \]

### Final Answer
Thus, \( 8 \text{ kg } 70 \text{ g} - 0.526 \text{ kg} = 7.544 \text{ kg} \).
