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 \( 14.57 \).
