Find the sum of 1/8 and -3/4 . can you please give an explanation would mean very well please

First, you have to make a common denominator, so change -3/4 to have the same denominator as 1/8.
to do this, multiply -3/4 by 2/2 to equal -6/8.

then add 1/8 + (-6/8), which becomes 1/8 - 6/8 = -5/8

First, find the least common denominator. In this case it would be 8. If you are multiplying 4 by 2 to get 8, you must also multiply the numerator by 2.
1/8 + -3(2)/4(2)
1/8 + -6/8
Write all numerators above the common denominator.
1-6/8
Calculate.
-5/8

Hope this helps!
