31/8 = 3 7/8

Explanation:

When there is "-" in front of a parenthesis, change the sign of each term in the parenthesis if you remove the parenthesis.

-1/8 - (-4) becomes -1/8 + 4

Then, change 4 into a fraction whose denominator is 8,

-1/8 + 4 becomes -1/8 + 32/8

Then, calculate

(-1+32)/8 = 31/8

:. 4-1/8 = 3 7/8

Explanation:

Remove the brackets. (neg x neg = gives a pos)

-1/8 - (-4)

-1/8 +4

This can also written as 4-1/8

As a whole number consists of 8/8, if 1/8 is taken away, there will be 7/8 left.

:. 4-1/8 = 3 7/8
