What is 1/4 - [-3/8] =

Mathematics

Norma-Jean [14]2 years ago

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}

Rationalize the denominator of the fraction and enter the new denominator below.<br><br>8/2-√12
Studentka2010 [4]
\frac{8}{2-\sqrt{12}}=\frac{8}{2-\sqrt{4\cdot3}}=\frac{8}{2-2\sqrt3}=\frac{8}{2(1-\sqrt3)}=\frac{4}{1-\sqrt3}\\\\\frac{4}{1-\sqrt3}\cdot\frac{1+\sqrt3}{1+\sqrt3}=\frac{4(1+\sqrt3)}{1^2-(\sqrt3)^2}=\frac{4(1+\sqrt3)}{1-3}=\frac{4(1+\sqrt3)}{-2}=-2(1+\sqrt3)}\\\\=-2-2\sqrt3



if\ \frac{8}{2}-\sqrt{12}=4-\sqrt{4\cdot3}=4-2\sqrt3
