With math and best gets brainliest. show work.

Well, we know the amount of cups of sugar it calls per 1/2 teaspoon, so all we need to do to find the amount of cups of sugar per teaspoon is multiply by 2, since 1/2 teaspoon * 2 = 1 teaspoon.

2/3 * 2 = 1 1/3

The unit rate is 1 1/3 cups per teaspoon
Hope that helped =)

Per teaspoon means per 1 teaspoon
we know that the ratio is
2/3:1/2
we want to know
x:1
so
make them equal since they are in same ratio and fractionify

ok so easy peasy
(2/3)/(1/2)=x
2/3 times 2/1=x
4/3=x
4/3 cup

or you could recognize that 1/2  times 2=1 so therefor 2/3 times 2=x=

answer is 4/3 cup per teaspoon
