Solve 13*3+14*20+15*15+16*2/3+20+15+2=

$$13 \times 3 + \frac { 14 \times 20 + 15 \times 15 + 16 \times 2 } { 3 + 20 + 15 + 2 } =$$

Evaluate

$$\frac{2097}{40}=52.425$$

Solution Steps

Multiply 13 and 3 to get 39.

$$39+\frac{14\times 20+15\times 15+16\times 2}{3+20+15+2}$$

Multiply 14 and 20 to get 280. Multiply 15 and 15 to get 225. Multiply 16 and 2 to get 32.

$$39+\frac{280+225+32}{3+20+15+2}$$

Add 280 and 225 to get 505.

$$39+\frac{505+32}{3+20+15+2}$$

Add 505 and 32 to get 537.

$$39+\frac{537}{3+20+15+2}$$

Add 3 and 20 to get 23.

$$39+\frac{537}{23+15+2}$$

Add 23 and 15 to get 38.

$$39+\frac{537}{38+2}$$

Add 38 and 2 to get 40.

$$39+\frac{537}{40}$$

Convert 39 to fraction \frac{1560}{40}.

$$\frac{1560}{40}+\frac{537}{40}$$

Since \frac{1560}{40} and \frac{537}{40} have the same denominator, add them by adding their numerators.

$$\frac{1560+537}{40}$$

Add 1560 and 537 to get 2097.

$$\frac{2097}{40}$$

Factor

$$\frac{3 ^ {2} \cdot 233}{2 ^ {3} \cdot 5} = 52\frac{17}{40} = 52.425$$
