MULTIPLICATION AND DIVISION WORD PROBLEMS WORKSHEET

Problem 1 :

If 15 switches can be packed in 3 boxes, find the numbers boxes required to pack 35 switches.

Solution :

There are 15 switches packed in 3 boxes.

Number of switches packed in 1 box :

= 15/3

= 5

Number of boxes required to pack 35 switches :

= 35/5

= 7

Problem 2 :

If there are 25 lbs. of a particular chemical in 7 bags, find the amount of chemical in lbs. in 35 bags.

Solution :

There are 25 lbs. of chemical in 7 bags.

7 bags ----> 25 lbs.

5(7 bags) ----> 5(25 lbs.)

35 bags ----> 125 lbs.

Amount of chemical in 35 bags is 125 lbs.

Problem 3 :

Mr. Alex divides $4500 equally into three parts. He gives one pat for his mother, one part for his father and one part is divided equally among his three daughters. Find the share of each daughter.

Solution :

$4500 is equally divided into three parts.

The value of each part :

= 4500/3

= $1500

Now, $1500 is divided equally among three daughters.

The share of each daughter :

= 1500/3

= $500

Problem 4 :

Six months before, Daniel divided $5000 equally into two parts. He invested one of the parts in stock X and other in stock Y. Now, investment in stock X is three times of the initial deposit and investment in stock Y is three-fourth of the initial deposit. Find the total value of both the investments now. 

Solution :

$5000 is divided equally into two parts.

The value of each part :

= 5000/2

= $2500

Total values of both the investments now :

= 3(2500) + (3/4)(2500)

= 7500 + 0.75(2500)

= 7500 + 1875

= $9375

Problem 5 :

To celebrate Christmas, Mrs. Jessica buys 12 pizzas for the students in her class. There are 30 students in the class  and each pizza has 5 slices. If each student gets equal amount pf pizza, find the number of slices each student gets. 

Solution :

1 pizza has 5 slices.

Total number of slices in 12 pizzas :

= 12 x 5

= 60

So, 60 slices have to divided among 30 students.

Number of slices each student gets :

= 60/30

= 2

Problem 6 :

Glen walks around a circular path which has the circumference of 120 feet. If he walks at a rate of 2 feet per, how many minutes will he take to complete 3 rounds around the circular path?

Solution :

Glen walks 2 feet in one sec.

Time taken to complete one round around the circular path :

= 120/2

= 60 seconds

Time taken to complete 3 rounds around the circular path :

= 3(60 seconds)

= 180 seconds

= (180/60) minutes

= 3 minutes

Problem 7 :

Ken shares 7 boxes of candy equally among her 3 kids and each kid gets 14 pieces of candy. Find the number of pieces of candy in each box.

Solution :

1 kid ----> 14 pieces

3(1 kid) ----> 3(14 pieces)

3 kids ----> 42 pieces

So, there are 42 pieces of candy in 7 boxes.

Number of pieces of candy in each box :

= 42/7

= 6

Problem 8 :

A person completes 7 units of a particular work in one day. If 8 people do the same work for 15 days, find the number of units of work completed.

Solution :

Number of units of work completed by 1 person in 1 day :

= 7

Number of units of the same work completed by 8 people in 1 day :

= 8 x 7

= 56

Number of units of work completed by 8 people in 15 days :

= 15 x 56

= 840

Problem 9 :

12 people can complete 780 units of work in 13 days. On average, how many units of work can be completed by one person in one day?

Solution :

Number of units of work completed by 12 people in 13 days :

= 780

Number of units of work completed by 12 people in 1 day :

= 780/13

= 60

Number of units of work completed by 1 person in 1 day :

= 60/12

= 5

Problem 10 :

If 80 ounces of gold can be melted in 15 minutes, find the amount of time in hours required to melt 100 lbs. of gold.

Solution :

1 lb. = 16 ounces

100(1 lb.) = 100(16 ounces)

100 lbs. = 1600 ounces

80 ounces of gold can be melted in 15 minutes.

80 ounces ----> 15 minutes

20(80 ounces) ----> 20(15 minutes)

1600 ounces ----> 300 minutes

(1600/16) lbs. ----> (300/60) hours

100 lbs. ----> 5 hours

It will take 5 hours to melt 100 lbs. of gold.
