Question

What is 1:3 and show how much lemon juice would be needed if you use 36 cups of water to make lemonade

Answer 1

If the 36=1 in 1:3 ;
1:3 = 1 x 36:3 x 36 =36:108
so you would need 108 cups of lemon juice.
If the 36=3 ;
36/3=12
1:3 = 1 x 12: 3 x 12 = 12:36
so you would need 12 cups of lemon juice.
