Solve 8.1-16div8+4.4(16-11.5(1div0.5))

$$8.1-16 \div 8+4.4(16-11.5(1 \div 0.5))$$

Evaluate

$$-24.7$$

Solution Steps

Divide 16 by 8 to get 2.

$$8.1-2+4.4\left(16-11.5\times \frac{1}{0.5}\right)$$

Subtract 2 from 8.1 to get 6.1.

$$6.1+4.4\left(16-11.5\times \frac{1}{0.5}\right)$$

Expand \frac{1}{0.5} by multiplying both numerator and the denominator by 10.

$$6.1+4.4\left(16-11.5\times \frac{10}{5}\right)$$

Divide 10 by 5 to get 2.

$$6.1+4.4\left(16-11.5\times 2\right)$$

Multiply 11.5 and 2 to get 23.

$$6.1+4.4\left(16-23\right)$$

Subtract 23 from 16 to get -7.

$$6.1+4.4\left(-7\right)$$

Multiply 4.4 and -7 to get -30.8.

$$6.1-30.8$$

Subtract 30.8 from 6.1 to get -24.7.

$$-24.7$$

Factor

$$-24.7$$
