Solve 40*2+50*3+60*4+50*7+80/1+2+3+4+5

$$\frac{ 40 \times 2+50 \times 3+60 \times 4+50 \times 7+80 }{ 1+2+3+4+5 }$$

Evaluate

$$60$$

Solution Steps

Multiply 40 and 2 to get 80. Multiply 50 and 3 to get 150. Multiply 60 and 4 to get 240. Multiply 50 and 7 to get 350.

$$\frac{80+150+240+350+80}{1+2+3+4+5}$$

Add 80 and 150 to get 230.

$$\frac{230+240+350+80}{1+2+3+4+5}$$

Add 230 and 240 to get 470.

$$\frac{470+350+80}{1+2+3+4+5}$$

Add 470 and 350 to get 820.

$$\frac{820+80}{1+2+3+4+5}$$

Add 820 and 80 to get 900.

$$\frac{900}{1+2+3+4+5}$$

Add 1 and 2 to get 3.

$$\frac{900}{3+3+4+5}$$

Add 3 and 3 to get 6.

$$\frac{900}{6+4+5}$$

Add 6 and 4 to get 10.

$$\frac{900}{10+5}$$

Add 10 and 5 to get 15.

$$\frac{900}{15}$$

Divide 900 by 15 to get 60.

$$60$$

Factor

$$2^{2}\times 3\times 5$$
