88*9:77-0’9

To solve the expression \( 88 \times 9 \div 77 - 0.9 \), follow the order of operations (PEMDAS/BODMAS). 1. First, calculate \( 88 \times 9 \): \[ 88 \times 9 = 792 \] 2. Next, divide by 77: \[ 792 \div 77 = 10.28571428571429 \, (\text{approximately } 10.29) \] 3. Finally, subtract 0.9: \[ 10.28571428571429 - 0.9 = 9.38571428571429 \, (\text{approximately } 9.39) \] Thus, the final result is approximately \( 9.39 \).
