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

Answers

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)

(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

Lila = 8 1/3 - 2 1/3
Lila = 6

Lila jumped 6 feet
