Evaulate: `15xx4-:3-:2xx7`

Answer

To evaluate the expression `15 x 4 ÷ 3 ÷ 2 x 7`, we will follow the order of operations step by step.

### Step-by-Step Solution:

1. **Write the expression clearly**:
\[ 15 \times 4 \div 3 \div 2 \times 7 \]

2. **Convert division to multiplication**:
We can rewrite the division as multiplication by using the reciprocal.
\[ 15 \times 4 \times \frac{1}{3} \times \frac{1}{2} \times 7 \]

3. **Multiply the first two numbers**:
Calculate \(15 \times 4\):
\[ 15 \times 4 = 60 \]
Now the expression is:
\[ 60 \times \frac{1}{3} \times \frac{1}{2} \times 7 \]

4. **Multiply by \(\frac{1}{3}\)**:
Calculate \(60 \div 3\):
\[ 60 \div 3 = 20 \]
Now the expression is:
\[ 20 \times \frac{1}{2} \times 7 \]

5. **Multiply by \(\frac{1}{2}\)**:
Calculate \(20 \div 2\):
\[ 20 \div 2 = 10 \]
Now the expression is:
\[ 10 \times 7 \]

6. **Final multiplication**:
Calculate \(10 \times 7\):
\[ 10 \times 7 = 70 \]

### Final Answer:
\[ \text{The final answer is } 70. \]
