Solve 7*12+103/5*12=?

$$7 \times 12 + 10 \frac { 3 } { 5 } \times 12 = ?$$

Evaluate

$$\frac{1056}{5}=211.2$$

Solution Steps

Multiply 7 and 12 to get 84.

$$84+\frac{10\times 5+3}{5}\times 12$$

Multiply 10 and 5 to get 50.

$$84+\frac{50+3}{5}\times 12$$

Add 50 and 3 to get 53.

$$84+\frac{53}{5}\times 12$$

Express \frac{53}{5}\times 12 as a single fraction.

$$84+\frac{53\times 12}{5}$$

Multiply 53 and 12 to get 636.

$$84+\frac{636}{5}$$

Convert 84 to fraction \frac{420}{5}.

$$\frac{420}{5}+\frac{636}{5}$$

Since \frac{420}{5} and \frac{636}{5} have the same denominator, add them by adding their numerators.

$$\frac{420+636}{5}$$

Add 420 and 636 to get 1056.

$$\frac{1056}{5}$$

Factor

$$\frac{2 ^ {5} \cdot 3 \cdot 11}{5} = 211\frac{1}{5} = 211.2$$
