Answer:
60% of the cake is banana .
Step-by-step explanation:
Formula
[tex]Percentage = \frac{Part\ value\times 100}{Total\ value}[/tex]
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
[tex]x = \frac{30}{5}[/tex]
x = 6
Total banana batter = 3x
= 3 × 6
= 18 cups
Part value = 18
Total value = 30
Put all the values in the formula
[tex]Percentage = \frac{18\times 100}{30}[/tex]
[tex]Percentage = \frac{1800}{30}[/tex]
Percentage = 60%
Therefore 60% of the cake is banana .
