Solve 1-[6*126/8(64-1)]

$$1 - [ \frac { 6 \times 126 } { 8 ( 64 - 1 ) } ]$$

Evaluate

$$-\frac{1}{2}=-0.5$$

Solution Steps

Cancel out 2\times 2 in both numerator and denominator.

$$1-\frac{3\times 63}{2\left(64-1\right)}$$

Multiply 3 and 63 to get 189.

$$1-\frac{189}{2\left(64-1\right)}$$

Subtract 1 from 64 to get 63.

$$1-\frac{189}{2\times 63}$$

Multiply 2 and 63 to get 126.

$$1-\frac{189}{126}$$

Reduce the fraction \frac{189}{126} to lowest terms by extracting and canceling out 63.

$$1-\frac{3}{2}$$

Convert 1 to fraction \frac{2}{2}.

$$\frac{2}{2}-\frac{3}{2}$$

Since \frac{2}{2} and \frac{3}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{2-3}{2}$$

Subtract 3 from 2 to get -1.

$$-\frac{1}{2}$$

Factor

$$-\frac{1}{2} = -0.5$$
