Question

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

Answer 1

$\frac{1}{4} - \frac{ - 3}{8} = \frac{5}{8}$
5/8 cross multiply on the top then multiply the denominator you get 20/32 reduce that it's 5/8

Answer 2

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

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

$\frac{5}{8}$
