How do you write 3/4 as a decimal?

##3/4=0.75##

Divide ##3## by ##4## to get ##0.75##

The division in this case is a bit tricky due to the fact that you have to divide something small ##3## into something bigger ##4##. as you can see at the start we borrow a zero to make our ##3## into a ##30## but we have to "signal" this loan by adding a ##0,## into the result; then we take another zero (in red) to form a ##20## and finish our division.
