Solve 4*5*6*7+8div9+1=

$$4 \times 5 \times 6 \times 7 + 8 \div 9 + 1 =$$

Evaluate

$$\frac{7577}{9}\approx 841.888888889$$

Solution Steps

Multiply 4 and 5 to get 20.

$$20\times 6\times 7+\frac{8}{9}+1$$

Multiply 20 and 6 to get 120.

$$120\times 7+\frac{8}{9}+1$$

Multiply 120 and 7 to get 840.

$$840+\frac{8}{9}+1$$

Convert 840 to fraction \frac{7560}{9}.

$$\frac{7560}{9}+\frac{8}{9}+1$$

Since \frac{7560}{9} and \frac{8}{9} have the same denominator, add them by adding their numerators.

$$\frac{7560+8}{9}+1$$

Add 7560 and 8 to get 7568.

$$\frac{7568}{9}+1$$

Convert 1 to fraction \frac{9}{9}.

$$\frac{7568}{9}+\frac{9}{9}$$

Since \frac{7568}{9} and \frac{9}{9} have the same denominator, add them by adding their numerators.

$$\frac{7568+9}{9}$$

Add 7568 and 9 to get 7577.

$$\frac{7577}{9}$$

Factor

$$\frac{7577}{3 ^ {2}} = 841\frac{8}{9} = 841.8888888888889$$
