Solve (15:5*4-7):5+11/(8*4-12):5

$$\frac { ( 15 : 5 \cdot 4 - 7 ) : 5 + 11 } { ( 8 \cdot 4 - 12 ) : 5 }$$

Evaluate

$$3$$

Solution Steps

Divide 15 by 5 to get 3.

$$\frac{\frac{3\times 4-7}{5}+11}{\frac{8\times 4-12}{5}}$$

Multiply 3 and 4 to get 12.

$$\frac{\frac{12-7}{5}+11}{\frac{8\times 4-12}{5}}$$

Subtract 7 from 12 to get 5.

$$\frac{\frac{5}{5}+11}{\frac{8\times 4-12}{5}}$$

Divide 5 by 5 to get 1.

$$\frac{1+11}{\frac{8\times 4-12}{5}}$$

Add 1 and 11 to get 12.

$$\frac{12}{\frac{8\times 4-12}{5}}$$

Multiply 8 and 4 to get 32.

$$\frac{12}{\frac{32-12}{5}}$$

Subtract 12 from 32 to get 20.

$$\frac{12}{\frac{20}{5}}$$

Divide 20 by 5 to get 4.

$$\frac{12}{4}$$

Divide 12 by 4 to get 3.

$$3$$

Factor

$$3$$
