$${ 5 }^{ 2 } \div 12 \times 3-7$$

Evaluate

$$-\frac{3}{4}=-0.75$$

Solution Steps

Calculate 5 to the power of 2 and get 25.

$$\frac{25}{12}\times 3-7$$

Express \frac{25}{12}\times 3 as a single fraction.

$$\frac{25\times 3}{12}-7$$

Multiply 25 and 3 to get 75.

$$\frac{75}{12}-7$$

Reduce the fraction \frac{75}{12} to lowest terms by extracting and canceling out 3.

$$\frac{25}{4}-7$$

Convert 7 to fraction \frac{28}{4}.

$$\frac{25}{4}-\frac{28}{4}$$

Since \frac{25}{4} and \frac{28}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{25-28}{4}$$

Subtract 28 from 25 to get -3.

$$-\frac{3}{4}$$

Factor

$$-\frac{3}{4} = -0.75$$
