## Complex fractions word problems worksheet - Solution

Problem 1 :

Maya wants to divide a 3/4 -pound box of trail mix into small bags. Each bag will hold 1/12 pound of trail mix. How many bags of trail mix can Maya fill ?

Solution :

Step 1 :

To get answer for the above question, we have to divide 3/4 by 1/12.

That is, we have to find the value of (3/4) / (1/12).

Step 2 :

Determine the sign of the quotient.

The quotient will be positive, because the signs of both numerator (3/4) and denominator (1/12) are same.

Step 3 :

Write the complex fraction as division :

(3/4) / (1/12)  =  (3/4) ÷ (1/12)

Step 4 :

Rewrite the above division as multiplication by taking the reciprocal of the second fraction.

(3/4) ÷ (1/12)  =  (3/4) x (12/1)

Step 5 :

Simplify

(3/4) x (12/1)  =  (3/1) x (3/1)

(3/4) x (12/1)  =  9

Hence, Maya can fill 9 bags of trail mix.

Problem 2 :

Cooper's bird feeder holds 9/10 of a cup of birdseed. Cooper is filling the bird feeder with a scoop that holds 3/10 of a cup. How many scoops of birdseed will Cooper put into the feeder?

Solution :

Step 1 :

To get answer for the above question, divide the total amount of birdseed by the size of each scoop.

That is, we have to find the value of (9/10) / (3/10).

Step 2 :

Determine the sign of the quotient.

The quotient will be positive, because the signs of both numerator (9/10) and denominator (3/10) are same.

Step 3 :

Write the complex fraction as division :

(9/10) / (3/10)  =  (9/10) ÷ (3/10)

Step 4 :

Rewrite the above division as multiplication by taking the reciprocal of the second fraction.

(9/10) ÷ (3/10)  =  (9/10) x (10/3)

Step 5 :

Simplify

(9/10) x (10/3)  =  (3/1) x (1/1)

(9/10) x (10/3)  =  3

Hence, Cooper will put 3 scoops of birdseed into the feeder.

Problem 3 :

A cookie factory uses 1/6 of a bag of flour in each batch of cookies. The factory used 1/2 of a bag of flour yesterday. How many batches of cookies did the factory make?

Solution :

Step 1 :

To get answer for the above question, divide the total amount of flour used by the amount used in each batch.

That is, we have to find the value of (1/2) / (1/6).

Step 2 :

Determine the sign of the quotient.

The quotient will be positive, because the signs of both numerator (1/2) and denominator (1/6) are same.

Step 3 :

Write the complex fraction as division :

(1/2) / (1/6)  =  (1/2) ÷ (1/6)

Step 4 :

Rewrite the above division as multiplication by taking the reciprocal of the second fraction.

(1/2) ÷ (1/6)  =  (1/2) x (6/1)

Step 5 :

Simplify

(1/2) x (6/1)  =  (1/1) x (3/1)

(1/2) x (6/1)  =  3

Problem 4 :

A factory uses 1/6 of a barrel of raisins in each batch of granola bars. Yesterday, the factory used 5/6 of a barrel of raisins. How many batches of granola bars did the factory make yesterday ?

Solution :

Step 1 :

To get answer for the above question, divide the total quantity of raisins used by the quantity needed for each batch.

That is, we have to find the value of (5/6) / (1/6).

Step 2 :

Determine the sign of the quotient.

The quotient will be positive, because the signs of both numerator (5/6) and denominator (1/6) are same.

Step 3 :

Write the complex fraction as division :

(5/6) / (1/6)  =  (5/6) ÷ (1/6)

Step 4 :

Rewrite the above division as multiplication by taking the reciprocal of the second fraction.

(5/6) ÷ (1/6)  =  (5/6) x (6/1)

Step 5 :

Simplify

(5/6) x (6/1)  =  (5/1) x (1/1)

(5/6) x (6/1)  =  5

Hence, the factory made 5 batches of granola bars yesterday.
