Question

5 3/4 - (-3 7/8) = H
What is H ?​

Answer 1

9 5/8.

Explanation:

5 3/4 - (-3 7/8)

= 5 3/4 + 3 7/8

= 5 + 3 + 3/4 + 7/8

= 8 + 3/4 + 7/8

The LCD of 4 and 8 is 8 so we get

8 + 6/8 + 7/8

= 8 + 13/8

= 8 + 1 5/8

= 9 5/8.

Answer 2

Explanation:

convert mixed fraction into improper fraction

`5(3)/(4)=(23)/(4)\\\\\\3(7)/(8)=(31)/(8)\\\\5(3)/(4)-[-3(7)/(8)]=(23)/(4)+(31)/(8)\\\\=(23*2)/(4*2)+(31)/(8)\\\\=(46)/(8)+(31)/(8)\\\\=(46+31)/(8)\\\\\\=(77)/(8)\\\\=9(5)/(8)`
