Solve -1/3+(1/4)^2=

$$- \frac { 1 } { 3 } + ( \frac { 1 } { 4 } ) ^ { 2 } =$$

Evaluate

$$-\frac{13}{48}\approx -0.270833333$$

Solution Steps

Calculate \frac{1}{4} to the power of 2 and get \frac{1}{16}.

$$-\frac{1}{3}+\frac{1}{16}$$

Least common multiple of 3 and 16 is 48. Convert -\frac{1}{3} and \frac{1}{16} to fractions with denominator 48.

$$-\frac{16}{48}+\frac{3}{48}$$

Since -\frac{16}{48} and \frac{3}{48} have the same denominator, add them by adding their numerators.

$$\frac{-16+3}{48}$$

Add -16 and 3 to get -13.

$$-\frac{13}{48}$$

Factor

$$-\frac{13}{48} = -0.2708333333333333$$
