Simplify (2 + 4 divided by 8 + 10) - 7 (2 + 4 divided by 8 + 10) - 7 equal

1 answer

To simplify the expression \((2 + 4 \div 8 + 10) - 7(2 + 4 \div 8 + 10)\), we first simplify the expression inside the parentheses.

  1. Calculate \(4 \div 8\): \[ 4 \div 8 = 0.5 \]

  2. Substitute this back into the expression: \[ 2 + 0.5 + 10 \]

  3. Calculate \(2 + 0.5 + 10\): \[ 2 + 0.5 = 2.5 \] \[ 2.5 + 10 = 12.5 \]

Now we substitute \(12.5\) back into the original expression: \[ (12.5) - 7(12.5) \]

Next, calculate \(7(12.5)\): \[ 7 \times 12.5 = 87.5 \]

Now, substitute this into the expression: \[ 12.5 - 87.5 \]

Finally, calculate: \[ 12.5 - 87.5 = -75 \]

Thus, the simplified expression is: \[ \boxed{-75} \]
