Answer:
1/3 cup sugar
Step-by-step explanation:
to find this out, we must first find the proportional relationship between the first 2 values of the sugar and the butter
2/3c sugar to 2 teaspoons butter
then we figure out what we changed on one side of the equation above and do the same on the other side
2/3c sugar = 2t butter
2t butter / 2 = 1t butter
now to apply this to the other side of the =
(2/3c sugar / 2) = (2t butter / 2)
1/3c sugar = 1t butter
this process is very versatile and can be used to find out many problems like this, say you need to figure out how much sugar you need for 4t butter, all you have to do is multiply instead of divide
hope this helps ya out with this and other future problems
