7•7:2

To solve the expression \( 7 \cdot 7 : 2 \), we first interpret the colon (:) as division. So the expression can be rewritten as: \[ 7 \cdot 7 \div 2 \] Now, calculate \( 7 \cdot 7 \): \[ 7 \cdot 7 = 49 \] Next, divide \( 49 \) by \( 2 \): \[ 49 \div 2 = 24.5 \] Thus, the result of \( 7 \cdot 7 : 2 \) is \( 24.5 \).
