# Word Problems on Multiplication

Word problems on multiplication for fourth grade students are solved here step by step.

Problem Sums Involving Multiplication:

1. 24 folders each has 56 sheets of paper inside them. How many sheets of paper are there altogether?

Solution:

We can add 56 sheets 24 times
OR
Since multiplication is repeated addition we can multiply 56 and 24 to get the answer.

[Sometime, more than one calculation is required.]

Therefore, altogether there are 1344 sheets.

2. A carton holds 24 packets of biscuits. Each packet has 12 biscuits. How many biscuits can be packed in 45 cartons?

In one carton we can pack 24 × 12 biscuits.
In 45 cartons, we can pack 24 × 12 × 45 biscuits.
24 × 12 = 288

 → 40 + 5Multiply by 5 Multiply by 40

Therefore, altogether there are 12,960 biscuits.

Consider the following Examples on Word Problems Involving Multiplication:

1. A book costs $67. How much will be paid for 102 such books? Solution: The cost of one book =$ 6 7                   6 7

Number of books                  = 1 0 2             × 1 0 2

The cost of 102 books          = $67 × 102 1 3 4 =$ 6834         + 6 7 0 0

6 8 3 4

Therefore, cost of 102 books = $6834 2. A bicycle costs$ 215. How much will be paid for 87 such bicycles?

Solution:

The cost of one bicycle            = $2 1 5 2 1 5 Number of bicycle = 8 7 × 8 7 The cost of 87 bicycles =$ 2 1 5 × 8 7        1 5 0 5

= $6834 + 1 7 2 0 0 1 8 7 0 5 Therefore, cost of 87 bicycles =$ 18705

3. The monthly salary of a man is $2,625. What is his annual income by salary? Solution: Monthly income =$2,625                   2 6 2 5

Annual income                 = $2,625 × 12 × 1 2 =$31,500                 5 2 5 0

+ 2 6 2 5 0

3 1 5 0 0

Therefore, annual income = $31,500 4. A chair costs$ 452 and a table costs $1750. What will be cost of 15 chairs and 30 tables? Solution: (i) Cost of one chair =$ 452

Cost of 15 chairs             = $452 × 15 =$ 6,780

(ii) Cost of one table        = $1,750 Cost of 30 tables =$ 1,750 × 30

= $52,500 Therefore, cost of 15 chairs and 30 tables =$ 6,780 + $52,500 =$ 59,280
