Solve 1/5+1/3*1/4

$$\frac{ 1 }{ 5 } + \frac{ 1 }{ 3 } \times \frac{ 1 }{ 4 }$$

Evaluate

$$\frac{17}{60}\approx 0.283333333$$

Solution Steps

Multiply \frac{1}{3} times \frac{1}{4} by multiplying numerator times numerator and denominator times denominator.

$$\frac{1}{5}+\frac{1\times 1}{3\times 4}$$

Do the multiplications in the fraction \frac{1\times 1}{3\times 4}.

$$\frac{1}{5}+\frac{1}{12}$$

Least common multiple of 5 and 12 is 60. Convert \frac{1}{5} and \frac{1}{12} to fractions with denominator 60.

$$\frac{12}{60}+\frac{5}{60}$$

Since \frac{12}{60} and \frac{5}{60} have the same denominator, add them by adding their numerators.

$$\frac{12+5}{60}$$

Add 12 and 5 to get 17.

$$\frac{17}{60}$$

Factor

$$\frac{17}{2 ^ {2} \cdot 3 \cdot 5} = 0.2833333333333333$$
