$$\frac { ( 82.5 \times 2 + 5 \times 78.2 \times 3 + 80 \times 3 ) } { 2 + 5 + 3 }$$

Evaluate

$$157.8$$

Solution Steps

Multiply 82.5 and 2 to get 165.

$$\frac{165+5\times 78.2\times 3+80\times 3}{2+5+3}$$

Multiply 5 and 78.2 to get 391.

$$\frac{165+391\times 3+80\times 3}{2+5+3}$$

Multiply 391 and 3 to get 1173.

$$\frac{165+1173+80\times 3}{2+5+3}$$

Add 165 and 1173 to get 1338.

$$\frac{1338+80\times 3}{2+5+3}$$

Multiply 80 and 3 to get 240.

$$\frac{1338+240}{2+5+3}$$

Add 1338 and 240 to get 1578.

$$\frac{1578}{2+5+3}$$

Add 2 and 5 to get 7.

$$\frac{1578}{7+3}$$

Add 7 and 3 to get 10.

$$\frac{1578}{10}$$

Reduce the fraction \frac{1578}{10} to lowest terms by extracting and canceling out 2.
