Jada has picked 1 cup of strawberries for a cake, which is enough for 3/4 of the cake. how many cups does she need for the whole cake?

Let's say that the number of cups of strawberries Jada needs for the whole cake is x. The problem says that 3/4 of the cake is equal to 1 cup of strawberries, so we can set up the following equation:
3/4x = 1
We can solve this equation by multiplying both sides of the equation with 4/3, so it cancels out with the 3/4. Make sure to do this to both sides!
So, you get:
x=4/3
Jada needs 4/3 cups of strawberries for the whole cake.
