1/4 - [-3/8]

\frac{1}{4}- (-\frac{3}{8})

Negative times negative become positive

\frac{1}{4} + \frac{3}{8}

Now to add fractions we make the denominator same

4  and 8 are in the denominator

Least common denominator of 4  and 8 is 8

To make denominators same , we multiply the numerator and denominator of first fraction by 2.

\frac{1*2}{4*2} + \frac{3}{8}

\frac{2}{8} + \frac{3}{8}

The denominators are same so we combine the numerators

\frac{2+3}{8}

\frac{5}{8}

You need to use a common denominator. The least common denominator of 11 and 22 is 22.

3/22 + -1/11 = 3/22 + -2/22 = 3/22 - 2/22 = 1/22
