Solve (13*5)+(14*7)+(15*9)+(16*4)+(17*7)+18/33

$$\frac{ (13 \times 5)+(14 \times 7)+(15 \times 9)+(16 \times 4)+(17 \times 7)+18 }{ 33 }$$

Evaluate

$$\frac{499}{33}\approx 15.121212121$$

Solution Steps

Multiply 13 and 5 to get 65. Multiply 14 and 7 to get 98. Multiply 15 and 9 to get 135. Multiply 16 and 4 to get 64. Multiply 17 and 7 to get 119.

$$\frac{65+98+135+64+119+18}{33}$$

Add 65 and 98 to get 163.

$$\frac{163+135+64+119+18}{33}$$

Add 163 and 135 to get 298.

$$\frac{298+64+119+18}{33}$$

Add 298 and 64 to get 362.

$$\frac{362+119+18}{33}$$

Add 362 and 119 to get 481.

$$\frac{481+18}{33}$$

Add 481 and 18 to get 499.

$$\frac{499}{33}$$

Factor

$$\frac{499}{3 \cdot 11} = 15\frac{4}{33} = 15.121212121212121$$
