1. What is the ratio of black to white squares? (1 mark)
I

2 : 4
1 : 2
black to white squares
theirs 2 black squares and 4 whites
put 2 first because its (black) to white
so we would have 2 : ? now we add the four to the other side
now we have 2 : 4
to simplify it we can half both sides witch will get us 1 : 2
