Question

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

Answer 1

we only need the percent

straberry:banana=2:3
2+3=5

banana=3 units
3/5=0.60=60%

60% is banana
and also 18cups is banana

Answer 2

60% of the cake is banana .

Explanation:

Formula

`Percentage = (Part\ value* 100)/(Total\ value)`

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 = (30)/(5)`

x = 6

Total banana batter = 3x

= 3 × 6

= 18 cups

Part value = 18

Total value = 30

Put all the values in the formula

`Percentage = (18* 100)/(30)`

`Percentage = (1800)/(30)`

Percentage = 60%

Therefore 60% of the cake is banana .
