Evaluate the following arithmetic expression:
`70-:2xx4-:7xx3`

Answer

To evaluate the arithmetic expression \( 70 \div 2 \times 4 \div 7 \times 3 \), we will follow the order of operations, commonly known as BODMAS/BIDMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).

### Step-by-Step Solution:

1. **Identify the expression**:
We start with the expression \( 70 \div 2 \times 4 \div 7 \times 3 \).

2. **Perform the divisions first**:
- First, calculate \( 70 \div 2 \):
\[ 70 \div 2 = 35 \]
- Now, replace \( 70 \div 2 \) in the expression:
\[ 35 \times 4 \div 7 \times 3 \]

3. **Continue with the next division**:
- Next, calculate \( 35 \div 7 \):
\[ 35 \div 7 = 5 \]
- Replace \( 35 \div 7 \) in the expression:
\[ 5 \times 4 \times 3 \]

4. **Perform the multiplications**:
- First, calculate \( 5 \times 4 \):
\[ 5 \times 4 = 20 \]
- Now, replace \( 5 \times 4 \) in the expression:
\[ 20 \times 3 \]
- Finally, calculate \( 20 \times 3 \):
\[ 20 \times 3 = 60 \]

5. **Final Result**:
The final result of the expression \( 70 \div 2 \times 4 \div 7 \times 3 \) is \( 60 \).
