Solve 4*(3.4div2)-(56div7)

$$4 \times (3.4 \div 2)-(56 \div 7)$$

Evaluate

$$-1.2$$

Solution Steps

Expand \frac{3.4}{2} by multiplying both numerator and the denominator by 10.

$$4\times \frac{34}{20}-\frac{56}{7}$$

Reduce the fraction \frac{34}{20} to lowest terms by extracting and canceling out 2.

$$4\times \frac{17}{10}-\frac{56}{7}$$

Express 4\times \frac{17}{10} as a single fraction.

$$\frac{4\times 17}{10}-\frac{56}{7}$$

Multiply 4 and 17 to get 68.

$$\frac{68}{10}-\frac{56}{7}$$

Reduce the fraction \frac{68}{10} to lowest terms by extracting and canceling out 2.

$$\frac{34}{5}-\frac{56}{7}$$

Divide 56 by 7 to get 8.

$$\frac{34}{5}-8$$

Convert 8 to fraction \frac{40}{5}.

$$\frac{34}{5}-\frac{40}{5}$$

Since \frac{34}{5} and \frac{40}{5} have the same denominator, subtract them by subtracting their numerators.

$$\frac{34-40}{5}$$

Subtract 40 from 34 to get -6.

$$-\frac{6}{5}$$

Factor

$$-1.2$$
