Solve (8-14):((7-12)+(15-12)7*7

$$( 8 - 14 ) : ( ( 7 - 12 ) + ( 15 - 12 ) 7 \cdot 7$$

Evaluate

$$-\frac{3}{71}\approx -0.042253521$$

Solution Steps

Subtract 14 from 8 to get -6.

$$\frac{-6}{7-12+\left(15-12\right)\times 7\times 7}$$

Subtract 12 from 7 to get -5.

$$\frac{-6}{-5+\left(15-12\right)\times 7\times 7}$$

Subtract 12 from 15 to get 3.

$$\frac{-6}{-5+3\times 7\times 7}$$

Multiply 3 and 7 to get 21.

$$\frac{-6}{-5+21\times 7}$$

Multiply 21 and 7 to get 147.

$$\frac{-6}{-5+147}$$

Add -5 and 147 to get 142.

$$\frac{-6}{142}$$

Reduce the fraction \frac{-6}{142} to lowest terms by extracting and canceling out 2.

$$-\frac{3}{71}$$
