There are 4 gallons of milk in the refrigerator, mrs. white uses 1/5 gallon of milk to make a batch of pancakes. how many batches of pancakes can she make with 4 gallons of milk?

She can make 20 batches of pancakes with 4 gallons of milk.

Solution:

Given that,

Quantity of milk in refrigerator = 4 gallons

Quantity of milk required to make a batch of pan cake =

Need to determine how many batches of pan cake Mrs.White can make using 4 gallons of milk.

Number of batches which can be made by gallons of Milk = 1

So number of batches which can be made by

So, number of batches which can be made by 4 gallons of milk = 4 multiplied by the number of batches which can be made by 1 gallons of milk =

Hence, she can make 20 batches of pancakes.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
