Question 883923
x/8 = q remainder 3


x/8 = q + 3/8


x = 8q + 3


-------------------------------------------------------


x = 8q + 3


3x = 3(8q + 3)


3x = 24q + 9


3x+3 = 24q + 9 +3


3x+3 = 24q + 12


(3x+3)/8 = (24q + 12)/8


(3x+3)/8 = 3q + 12/8


(3x+3)/8 = 3q + 8/8 + 4/8


(3x+3)/8 = 3q + 1 + 4/8


(3x+3)/8 = (3q + 1) + <font color="red">4</font>/8


-------------------------------------------------------


So the remainder is <font color="red">4</font>
