I have 5 lbs of butter it takes 3/4 lb to make a batch of cookies how many batches can I make

Question

I have 5 lbs of butter it takes 3/4 lb to make a batch how many batches can I make 

Answer 1

If we divide 5 by 3/4, this will tell us how many batches can be made with 5 lb of butter

 

5 ÷ 3/4 = 5 * 4/3 = 20/3 = 6 2/3 batches of cookies can be made with 5 lb of butter

Answer 2

So, to solve this you will be dividing how much you have by how much it takes to make a batch of cookies.

 

you have 5lbs and it takes 3/4 lbs

 

When dealing with fractions it is important to note that even whole numbers are fractions with a 1 in the denominator.

 

so, 5 = 5/1

Now, let us set up our equation.

(what we have)/(what we need) = (number of batches)

(5/1)÷(3/4)

 

Now it is also important to remember that when you are dividing fractions, you can flip the fraction on the right(or on the bottom depending how your division is written) and turn it into multiplication.

 

(5/1)÷(3/4) = (5/1) × (4/3)

 

Multiply the numerators together and the denominators together to get

 

(5/1) × (4/3) = 20/3

 

Now, every fraction is division. So, now we can divide 20 by 3.

 

3 goes into 20, 6 times with 2 left over

 

so, 20/3 = 6 and 2/3

 

what this means is that we can make 6 full batches and 2/3 of another batch.

(5/1)÷(3/4)
