Solve 9*8-9*15*0.02/900*(1-0.15)

$$\frac { 9 \times 8 - 9 \times 15 \times 0.02 } { 900 \times ( 1 - 0.15 ) }$$

Evaluate

$$\frac{77}{850}\approx 0.090588235$$

Solution Steps

Multiply 9 and 8 to get 72.

$$\frac{72-9\times 15\times 0.02}{900\left(1-0.15\right)}$$

Multiply 9 and 15 to get 135.

$$\frac{72-135\times 0.02}{900\left(1-0.15\right)}$$

Multiply 135 and 0.02 to get 2.7.

$$\frac{72-2.7}{900\left(1-0.15\right)}$$

Subtract 2.7 from 72 to get 69.3.

$$\frac{69.3}{900\left(1-0.15\right)}$$

Subtract 0.15 from 1 to get 0.85.

$$\frac{69.3}{900\times 0.85}$$

Multiply 900 and 0.85 to get 765.

$$\frac{69.3}{765}$$

Expand \frac{69.3}{765} by multiplying both numerator and the denominator by 10.

$$\frac{693}{7650}$$

Reduce the fraction \frac{693}{7650} to lowest terms by extracting and canceling out 9.
