The ratio of strawberry to banana batter is 2: 3. we need 30 cups of batter total. what percent of the cake is banana?

60% of the cake is banana .

Step-by-step explanation:

Formula

As given

The ratio of strawberry to banana batter is 2:3.

we need 30 cups of batter total.

Let us assume that x be the scalar multiple of the strawberry to banana batter .

Total banana batter = 3x

Total strawberry batter = 2x

2x + 3x = 30

5x = 30

x = 6

Total banana batter = 3x

                                 = 3 × 6

                                 = 18 cups

Part value = 18

Total value = 30

Put all the values in the formula

Percentage = 60%

Therefore 60% of the cake is banana .
