Solve 1/20*(2*32+4*36+9*40+4*44+48)

$$\frac { 1 } { 20 } \times ( 2 \times 32 + 4 \times 36 + 9 \times 40 + 4 \times 44 + 48 )$$

Evaluate

$$\frac{198}{5}=39.6$$

Solution Steps

Multiply 2 and 32 to get 64. Multiply 4 and 36 to get 144. Multiply 9 and 40 to get 360. Multiply 4 and 44 to get 176.

$$\frac{1}{20}\left(64+144+360+176+48\right)$$

Add 64 and 144 to get 208.

$$\frac{1}{20}\left(208+360+176+48\right)$$

Add 208 and 360 to get 568.

$$\frac{1}{20}\left(568+176+48\right)$$

Add 568 and 176 to get 744.

$$\frac{1}{20}\left(744+48\right)$$

Add 744 and 48 to get 792.

$$\frac{1}{20}\times 792$$

Multiply \frac{1}{20} and 792 to get \frac{792}{20}.

$$\frac{792}{20}$$

Reduce the fraction \frac{792}{20} to lowest terms by extracting and canceling out 4.

$$\frac{198}{5}$$

Factor

$$\frac{2 \cdot 3 ^ {2} \cdot 11}{5} = 39\frac{3}{5} = 39.6$$
