Class 3 Mathematics - Multiplication and Unitary Method

The answer of 11 x 2 x 22 will be 484, which is same as the answer of 22 x 11 x 2. So, if we change the place of the numbers to be multiplied, answer will remain same.

This is the right answer. To get the answer, student had to multiply number of toffees from the cost of each toffee.15 x 3 = 45.So, the cost of all toffees will be Rs. 45.

This is the right answer. If we multiply 6 by 5 we will get 30. And to make the equation correct we should multiply 3 by the number which will give answer 30, and that number will be 10.      6 x 5 = 10 x 3          i.e. 30 = 30

This is the right answer. When we multiply 11 with 11 we will get 121.           11 x 11= 121

This is the right answer. To solve this question first we have to find out the cost of each doll. So to get the answer, first we have to divide 10 by 5 [i.e.10/5 = Rs.2].

So, to get the cost of 8 dolls we have to multiply 8 by Rs. 2. [i.e. 8 x Rs.2 = Rs.16.]

This is the right answer. To get the amount that shopkeeper will return to her, first we have to calculate the total cost of sweets. i.e.45 x 5 = 225.Now, we have to subtract this amount from the amount that she gave to shopkeeper.i.e. 230- 225 = 5.So, shopkeeper will return to her Rs. 5

This is the right answer. Multiplication is repeated addition. Here 8 is getting added 6 times, so to make it simple if we multiply 6 from 8 we will get the same answer.

This is the right answer. Here to find out the weight of bricks that truck is carrying, we have to multiply the weight of each brick by the total number of bricks.i.e.500 x 2 = 1000 Kg

This is the right answer. As to get the cost of all four packs, we have to multiply 80 by 4, i.e.80 x 4 = Rs.320

This is the right answer. We have to divide 4444 by 2 as a pair means 2 balls. 4444 / 2 = 2222

This is the right answer. To get the answer, we have to multiply the number of beads & number of necklaces.16 x 8 = 128

This is the right answer. As if we multiply 100 by 1000 we will get 100000.

This is the correct answer. As to get the total amount collected from the student's club we have to multiply the number of students by the amount to be collected by each student member. i.e. 352 x 22 = 7150.

This is the right answer. If we multiply both figures and the subtract it we will get 279. 140 x 140 = 19600
139 x 139 = 19321So, 19600- 19321 = 279.

This is the right answer. If we multiply the number with 1 we will get the same number.
