Solve 50-1/2+4/5+25

$$50 - 1 / 2 + 4 / 5 + 25$$

Evaluate

$$\frac{753}{10}=75.3$$

Solution Steps

Convert 50 to fraction \frac{100}{2}.

$$\frac{100}{2}-\frac{1}{2}+\frac{4}{5}+25$$

Since \frac{100}{2} and \frac{1}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{100-1}{2}+\frac{4}{5}+25$$

Subtract 1 from 100 to get 99.

$$\frac{99}{2}+\frac{4}{5}+25$$

Least common multiple of 2 and 5 is 10. Convert \frac{99}{2} and \frac{4}{5} to fractions with denominator 10.

$$\frac{495}{10}+\frac{8}{10}+25$$

Since \frac{495}{10} and \frac{8}{10} have the same denominator, add them by adding their numerators.

$$\frac{495+8}{10}+25$$

Add 495 and 8 to get 503.

$$\frac{503}{10}+25$$

Convert 25 to fraction \frac{250}{10}.

$$\frac{503}{10}+\frac{250}{10}$$

Since \frac{503}{10} and \frac{250}{10} have the same denominator, add them by adding their numerators.

$$\frac{503+250}{10}$$

Add 503 and 250 to get 753.

$$\frac{753}{10}$$

Factor

$$\frac{3 \cdot 251}{2 \cdot 5} = 75\frac{3}{10} = 75.3$$
