Solve 100+15div7*3-12=

$$100 + 15 \div 7 \times 3 - 12 =$$

Evaluate

$$\frac{661}{7}\approx 94.428571429$$

Solution Steps

Express \frac{15}{7}\times 3 as a single fraction.

$$100+\frac{15\times 3}{7}-12$$

Multiply 15 and 3 to get 45.

$$100+\frac{45}{7}-12$$

Convert 100 to fraction \frac{700}{7}.

$$\frac{700}{7}+\frac{45}{7}-12$$

Since \frac{700}{7} and \frac{45}{7} have the same denominator, add them by adding their numerators.

$$\frac{700+45}{7}-12$$

Add 700 and 45 to get 745.

$$\frac{745}{7}-12$$

Convert 12 to fraction \frac{84}{7}.

$$\frac{745}{7}-\frac{84}{7}$$

Since \frac{745}{7} and \frac{84}{7} have the same denominator, subtract them by subtracting their numerators.

$$\frac{745-84}{7}$$

Subtract 84 from 745 to get 661.

$$\frac{661}{7}$$

Factor

$$\frac{661}{7} = 94\frac{3}{7} = 94.42857142857143$$
