2)As a playgroup worker, if I increase the amount of apple juice I am serving at the playgroup from 25 ml to 100 ml, how much should I increase the the orange juice to, to keep the quantities in the same proportion? The orange juice is 50 ml to start with.
Multiply the orange by 2 to get same amount as the apple

3/4 = 12/16 or 4/9 = 16/32
Multiplying diagonally(Diagram on the picture)

Doing ti Horizontally (diagram on the picture)
Doing it vertically( Diagram is on the side)
