Solve 4*(15div7)-(6+2)]div(-1-4)}

$$4 \times ( 15 \div 7 ) - ( 6 + 2 ) ] \div ( - 1 - 4 ) \}$$

Evaluate

$$\frac{4}{7}\approx 0.571428571$$

Solution Steps

Express 4\times \frac{15}{7} as a single fraction.

$$\frac{4\times 15}{7}-\left(6+2\right)$$

Multiply 4 and 15 to get 60.

$$\frac{60}{7}-\left(6+2\right)$$

Add 6 and 2 to get 8.

$$\frac{60}{7}-8$$

Convert 8 to fraction \frac{56}{7}.

$$\frac{60}{7}-\frac{56}{7}$$

Since \frac{60}{7} and \frac{56}{7} have the same denominator, subtract them by subtracting their numerators.

$$\frac{60-56}{7}$$

Subtract 56 from 60 to get 4.

$$\frac{4}{7}$$

Factor

$$\frac{2 ^ {2}}{7} = 0.5714285714285714$$
