Question

Jada has picked 1 cup of strawberries for a cake, which is enough for ¾ of the cake. How many cups does she need for the whole cake?

Answer 1

she needs 1/4 more or .25cup more for the whole cake

Answer 2

she needs 1
`(1)/(3)` cup of strawberries

Explanation:

To find the number of cups needed, we will simply solve using proportion

From the question, Jade picked 1 cup of strawberries for 3/4 of a cake

and we are asked to find the number of cups needed for a whole cake

Let x be the number of cups needed for the whole cake

`(3)/(4) cake` = 1 cup of strawberries

1 cake = x

Cross multiply

`(3)/(4)` × x = 1 × 1

`(3x)/(4)` = 1

cross multiply

3x =4

To get the value of x, we simply divide both-side of the equation by 3

`(3x)/(3)` =
`(4)/(3)`

(On the left-hand side of the equation, 3 will cancel out 3 leaving us with x and on the right-hand side of the equation 4 will be divided by 3 which will give us 1
`(1)/(3)` )

x = 1
`(1)/(3)`

Therefore 1
`(1)/(3)` cup of strawberries is needed for the whole cake.
