Evaluate the following arithmetic expression:
`120-:3-:5xx7-:4`

Answer

To evaluate the arithmetic expression \( 120 \div 3 \div 5 \times 7 \div 4 \), we will follow the order of operations step by step.

### Step 1: Start with the first division
We begin with the first operation, which is \( 120 \div 3 \).

\[ 120 \div 3 = 40 \]

### Step 2: Continue with the next division
Now we take the result from Step 1 and divide it by 5.

\[ 40 \div 5 = 8 \]

### Step 3: Multiply by 7
Next, we take the result from Step 2 and multiply it by 7.

\[ 8 \times 7 = 56 \]

### Step 4: Divide by 4
Finally, we take the result from Step 3 and divide it by 4.

\[ 56 \div 4 = 14 \]

### Final Answer
Thus, the final answer for the expression \( 120 \div 3 \div 5 \times 7 \div 4 \) is:

\[ \boxed{14} \]
