Evaluate

$$\frac{28873}{1200}\approx 24.060833333$$

Solution Steps

Add 6.13 and 7.9 to get 14.03.

$$\frac{14.03+9.99+12.15+15.02+17.5+20.92+26.86+31.11+38.85+47.25+55.05}{12}$$

Add 14.03 and 9.99 to get 24.02.

$$\frac{24.02+12.15+15.02+17.5+20.92+26.86+31.11+38.85+47.25+55.05}{12}$$

Add 24.02 and 12.15 to get 36.17.

$$\frac{36.17+15.02+17.5+20.92+26.86+31.11+38.85+47.25+55.05}{12}$$

Add 36.17 and 15.02 to get 51.19.

$$\frac{51.19+17.5+20.92+26.86+31.11+38.85+47.25+55.05}{12}$$

Add 51.19 and 17.5 to get 68.69.

$$\frac{68.69+20.92+26.86+31.11+38.85+47.25+55.05}{12}$$

Add 68.69 and 20.92 to get 89.61.

$$\frac{89.61+26.86+31.11+38.85+47.25+55.05}{12}$$

Add 89.61 and 26.86 to get 116.47.

$$\frac{116.47+31.11+38.85+47.25+55.05}{12}$$

Add 116.47 and 31.11 to get 147.58.

$$\frac{147.58+38.85+47.25+55.05}{12}$$

Add 147.58 and 38.85 to get 186.43.

$$\frac{186.43+47.25+55.05}{12}$$

Add 186.43 and 47.25 to get 233.68.

$$\frac{233.68+55.05}{12}$$

Add 233.68 and 55.05 to get 288.73.

$$\frac{288.73}{12}$$

Expand \frac{288.73}{12} by multiplying both numerator and the denominator by 100.

$$\frac{28873}{1200}$$

Factor

$$\frac{13 \cdot 2221}{3 \cdot 2 ^ {4} \cdot 5 ^ {2}} = 24\frac{73}{1200} = 24.060833333333335$$
