Question

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

Answer 1

`(1)/(4) - ( - 3)/(8) = (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]

`(1)/(4)- (-(3)/(8))`

Negative times negative become positive

`(1)/(4) + (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.

`(1*2)/(4*2) + (3)/(8)`

`(2)/(8) + (3)/(8)`

The denominators are same so we combine the numerators

`(2+3)/(8)`

`(5)/(8)`
