Subtract 3/8 - (-5 ¼)

5 and 5/8

I just did on an extreme calculator cuz im bored

5 5/8

The subtraction symbol infront of the parentheses will be distributed to the - 5 1/4 making it positive

then you would multiply the 1/4 by 2 to give you 2/8 and you add 3/8 to the 2/8 giving you 5/8

So now you would put the numbers together which are 5 and 5/8
