beks73 [17]

Answer:

The ratio of the amount of flour to the amount of buttermilk=99:1

Step-by-step explanation:

Step 1: Determine quantity for each recipe

Quantity of flour=66 cups

Quantity of buttermilk=2/3 cups

Step 2: Calculate the total quantity of recipe

The expression for the total quantity is;

T=f+b

where;

T=total quantity of recipe

f=quantity of flour

b=quantity of buttermilk

In our case;

T=unknown

f=66 cups

b=2/3 cups

replacing;

T=(66)+(2/3)=66 2/3 cups

Step 3: Determine fraction of each

fraction of buttermilk=(2/3)/(66 2/3)=1/100

fraction of flour=66/(66 2/3)=99/100

Step 4: Determine ratio of flour to buttermilk

Amount of flour:amount of buttermilk

(99/100):(1/100)

The ratio of the amount of flour to the amount of buttermilk=99:1
