Question

You have a recipe for crepes. The recipe makes 8 crepes. You need 100 crepes for a school event. Increase the recipe proportionally to make 100 crepes.

Answer 1

first let's find the ratio, how much we need to increase the recipe

the recipe is for 8 crepes, so if we divide it by 8, will be for 1 crepe

and then if we multiply it by 100 will be for 100 crepes, so the ratio is:

`\begin{gathered} x\cdot(100)/(8) \\ or\text{ x}\cdot(25)/(2) \end{gathered}`

x: the value of the recipe.

So now all we need to do is multiply the recipe by 25/2

Flour

original: 1 cup

for 100 crepes:

1*25/2 = 25/2

25/2 is 12 1/2 so Tile 1

Eggs

original:2

for 100 crepes:

2*25/2 = 25 so Tile 2

Milk

original: 1/2 cups

for 100 crepes:

1/2*25/2= 6 1/4 so Tile 3a

Water

Original: 1/3 cups

for 100 crepes:

1/3*25/2= 4 1/6 So Tile 4

Salt

Original: 1/4 teaspoon

for 100 crepes:

1/4*25/2= 3 1/8 so Tile 5
