Solve 3/2+4*3*5+4*99

$$3 / 2 + 4 \times 3 \cdot 5 + 4 \cdot 99$$

Evaluate

$$\frac{915}{2}=457.5$$

Solution Steps

Multiply 4 and 3 to get 12. Multiply 4 and 99 to get 396.

$$\frac{3}{2}+12\times 5+396$$

Multiply 12 and 5 to get 60.

$$\frac{3}{2}+60+396$$

Convert 60 to fraction \frac{120}{2}.

$$\frac{3}{2}+\frac{120}{2}+396$$

Since \frac{3}{2} and \frac{120}{2} have the same denominator, add them by adding their numerators.

$$\frac{3+120}{2}+396$$

Add 3 and 120 to get 123.

$$\frac{123}{2}+396$$

Convert 396 to fraction \frac{792}{2}.

$$\frac{123}{2}+\frac{792}{2}$$

Since \frac{123}{2} and \frac{792}{2} have the same denominator, add them by adding their numerators.

$$\frac{123+792}{2}$$

Add 123 and 792 to get 915.

$$\frac{915}{2}$$

Factor

$$\frac{3 \cdot 5 \cdot 61}{2} = 457\frac{1}{2} = 457.5$$
