Solve 5+[3+7)*2/7=

$$5 + [ 3 + 7 ) \times \frac { 2 } { 7 } =$$

Evaluate

$$\frac{55}{7}\approx 7.857142857$$

Solution Steps

Add 3 and 7 to get 10.

$$5+10\times \frac{2}{7}$$

Express 10\times \frac{2}{7} as a single fraction.

$$5+\frac{10\times 2}{7}$$

Multiply 10 and 2 to get 20.

$$5+\frac{20}{7}$$

Convert 5 to fraction \frac{35}{7}.

$$\frac{35}{7}+\frac{20}{7}$$

Since \frac{35}{7} and \frac{20}{7} have the same denominator, add them by adding their numerators.

$$\frac{35+20}{7}$$

Add 35 and 20 to get 55.

$$\frac{55}{7}$$

Factor
