256-53:5

To solve the expression \( 256 - 53 : 5 \), we follow the order of operations (PEMDAS/BODMAS):

1. First, we perform the division \( 53 : 5 \): \[ 53 \div 5 = 10.6 \]

2. Next, we subtract that result from 256: \[ 256 - 10.6 = 245.4 \]

Therefore, the result of \( 256 - 53 : 5 \) is \( 245.4 \).
