Solve 1/5+1/2*1/4=

$$\frac { 1 } { 5 } + \frac { 1 } { 2 } \times \frac { 1 } { 4 } =$$

Evaluate

$$\frac{13}{40}=0.325$$

Solution Steps

Multiply \frac{1}{2} times \frac{1}{4} by multiplying numerator times numerator and denominator times denominator.

$$\frac{1}{5}+\frac{1\times 1}{2\times 4}$$

Do the multiplications in the fraction \frac{1\times 1}{2\times 4}.

$$\frac{1}{5}+\frac{1}{8}$$

Least common multiple of 5 and 8 is 40. Convert \frac{1}{5} and \frac{1}{8} to fractions with denominator 40.

$$\frac{8}{40}+\frac{5}{40}$$

Since \frac{8}{40} and \frac{5}{40} have the same denominator, add them by adding their numerators.

$$\frac{8+5}{40}$$
