Question 16: Multiply each of the following:

Question 17: Fill in the boxes:

Question 18: Estimate the following sums to the nearest hundreds:
(Also, compare the estimated sums with the actual sums.)

• 375 + 236 = 611
400 + 200 = 600
611 > 600
• 273 + 504 = 777
300 + 500 = 800
800 > 777
• 173 + 58 = 231
200 + 100 = 300
231 < 300
• 287 + 189 = 476
300 + 200 = 400
476 > 400

Question 19: Estimate the following to the nearest hundreds:
(Also, compare the estimated differences with the actual differences.)

• 879 - 705 = 174
900 - 700 = 200
174 < 200
• 613 - 156
613 - 156 = 457
600 - 200 = 400
457 > 400
• 875 - 261 = 614
900 - 300 = 600
614 > 600
• 352 - 256 = 96
400 - 300 = 100
96 < 100

Question 20: Estimate each of the following products by rounding off each number to the nearest tens:

• 41 x 16
40 x 20 = 800
• 37 x 22
40 x 20 = 400

Question 21: A matchbox contains 50 sticks. How many sticks are there in 9 such matchboxes?

1 matchbox contains = 50 sticks
Sticks in 9 matchboxes = 50 x 9 = 450

Question 22: There are 75 toffees in a box. How many toffees will there be in 5 such boxes?

Total number of toffees in a box = 75
Total number of toffees in 5 boxes = 75 x 5 = 375

Question 23: There are 30 days in a month. How many days are there in 6 months?

Total number of days in a month= 30
Total number of days 6 months = 30 x 6 = 180

Question 24: A car can travel 60 km in one hour. How far will it travel in 3 hours?

A car can travel in one hour = 60 km
A car travels in 3 hours = 60 x 3 = 180 km

Question 25: A candle factory produces 55 candles in a day. How many candles will this factory produce in 6 days?

## FAQs on Multiplication Class 1 Worksheet Mental Maths

 1. How do you multiply two numbers using the standard algorithm?
Ans. To multiply two numbers using the standard algorithm, you multiply the ones digit of the second number by each digit of the first number, then do the same for the tens digit, and so on. Finally, you add up all the partial products to get the final answer.
 2. What is the significance of the commutative property in multiplication?
Ans. The commutative property in multiplication states that changing the order of the factors does not change the product. This property allows us to simplify calculations and easily switch the positions of numbers when multiplying.
 3. How can multiplication be applied in real-life situations?
Ans. Multiplication is used in various real-life situations such as calculating total costs when buying multiple items, determining the area of a rectangle, or finding out how many hours are in a given number of days.
 4. What are some common mistakes students make when multiplying numbers?
Ans. Some common mistakes students make when multiplying numbers include forgetting to carry over when multiplying two-digit numbers, mixing up the order of the factors, or incorrectly placing the decimal point in decimal multiplication.
 5. Can you explain the concept of multiplying by multiples of 10?
Ans. When multiplying by multiples of 10, you can simply add the number of zeros in the multiple of 10 to the original number. For example, when multiplying 25 by 10, you add one zero to get 250.
