We will learn how to solve step-by-step the word problems on multiplication and division of whole numbers. We know, we need to do multiplication and division in our daily life. Let us solve some word problem examples.
Word problems on multiplying and dividing of large numbers:
1. The cost of a chair is $980.50. Find the cost of such 2035 chairs.
Cost of a chair = 980.50
Number of chairs = × 2035
Cost of 2035 chairs = 1995317.50
Therefore, cost of 2035 chairs is $1995317.50.
2. A tyre factory produces 6348 tyres a day. How many tyres will the factory produce in 460 days?
Number of tyres a tyre factory produces in one day = 6348
Number of day = × 460
Total number of tyres produces in 460 days = 2920080
Therefore, the tyre factory will produce 2920080 tyres in 460 days.
3. 470988 books are to be arranged equally in shelves. If 378 books are arranged in each shelf, how many shelves will be needed?
Total number of books = 470988
Number of books arranged in each shelf = 378
Number of shelves needed = 470988 ÷ 378
Therefore, 1246 shelves needed to arrange 470988 books equally.
4. The cost of 534 train tickets was $457104. Find the cost of one ticket?
Number of train tickets = 534
Cost of 534 train tickets = $457104
Cost of 1 train ticket = 457104 ÷ 534
Therefore, cost of one train ticket is $856.
