There are 20.5 cups of batter in the bowl. this represents 0.4 of the entire amount of batter needed for a recipe. how many cups of batter are needed?

51.25 cups

Step-by-step explanation:

From the statement above, 20.5 cups is 0.4 of the entire amount of batter

let x = the total amount of batter.

Interpreting the above question mathematically;

0.4 of x = 20.5

0.4 × x  =  20.5

0.4x  =   20.5

divide both-side of the equation by 0.4, in order for the x variable to stand alone

0.4x/0.4 = 20.5/0.4

x =  51.25

Therefore 51.25 cups of batter are needed.

Number of cups of batter in the bowl = 20.5

As stated, this 20.5 represents 0.4 of the entire amount of batter needed for a recipe it means ; 0.4 of 20.5 = x

Let x represents the amount of batter needed for recipe

So,

Hence , 8.2 cups of batter are needed for the recipe.
