5-3:7+10

To solve the expression \( 5 - 3 : 7 + 10 \), we need to follow the order of operations (PEMDAS/BODMAS).

First, we clarify whether "3:7" means division or a ratio. Here, we will assume it means division. Thus, the expression can be rewritten as:

\[ 5 - \frac{3}{7} + 10 \]

Now, we perform the operations step by step:

1. Calculate \( \frac{3}{7} \):

   • \( 0.42857 \) (approx)

2. Substitute back into the expression: \[ 5 - 0.42857 + 10 \]

3. Calculate \( 5 - 0.42857 \):

   • \( 4.57143 \) (approx)

4. Now, add \( 10 \): \[ 4.57143 + 10 = 14.57143 \]

So, the answer to the expression \( 5 - 3 : 7 + 10 \) is approximately \( 14.57 \).
