## If the product of two whole numbers is 1, can we say that one or both of them will be 1. Justify through examples

Dear student the solution to your question is here - Example : (i) 0 × 1 = 0 (ii) 1 × 2 = 2 (iii) 1 × 1 = 1 In above given example all are product of whole number i.e. 0, 2 and 1 after observing all of them we get 1 from example (iii) is 1 X 1 = 1 From this we can conclude that if the product of twoRead more

Dear student the solution to your question is here –

Example :

(i) 0 × 1 = 0

(ii) 1 × 2 = 2

(iii) 1 × 1 = 1

In above given example all are product of whole number i.e. 0, 2 and 1 after observing all of them we get 1 from example (iii) is 1 X 1 = 1 From this we can conclude that if the product of two whole numbers is 1, we can say that both of them will be 1.

Hope you understand 🙂

Dear student the solution to your question is here - Example : (i) 2 × 0 = 0 (ii) 0 × 0 = 0 (iii) 3 × 4 = 12 After observing the above examples in example (i) 2 and 0 are whole numbers in example (ii) 0 and 0 are whole number and their product is zero, but in example (iii) 3 and 4 are whole numbersRead more

Dear student the solution to your question is here –

Example :

(i) 2 × 0 = 0

(ii) 0 × 0 = 0

(iii) 3 × 4 = 12

After observing the above examples in example

(i) 2 and 0 are whole numbers in example

(ii) 0 and 0 are whole number and their product is zero, but in example

(iii) 3 and 4 are whole numbers but their product is not equal to zero.

We have come to a connection that if the product of two whole number is zero we can say that one or both of them will be zero.

Hope this answer will help you to clear all your doubts about this question 🙂

See less## Which of the following will not represent zero

Here is the answer to your question - 1 + 0 = 1, 0 × 0 = 0, 0/2 = 0, 10 - 10/2 = 0/2 = 0 1 + 0 does not/will not represent zero.

Here is the answer to your question –

1 + 0 = 1,

See less0 × 0 = 0,

0/2 = 0,

10 – 10/2 = 0/2 = 0

1 + 0 does not/will not represent zero.

## A vendor supplies 32 litres of milk to a hotel in the morning and 68 litres of milk in the evening. if the milk costs 45 per litre, how much money is due to the vendor per day

Dear student, the problem can be solved as follows : - The cost of milk is RS 45 per litre. Due money for the morning is for 32 litres of milk is = 45 × 32 Due money for the evening is for 68 litres of milk is = 45 × 68 Therefore total due money, = 45 × 32 + 45 × 68 = 45 (32 + 68) (Distributivity ofRead more

Dear student, the problem can be solved as follows : –

The cost of milk is RS 45 per litre.

Due money for the morning is for 32 litres of milk is = 45 × 32

Due money for the evening is for 68 litres of milk is = 45 × 68

Therefore total due money,

= 45 × 32 + 45 × 68 = 45 (32 + 68)

(Distributivity of multiplication over addition)

∴ Rs. 4500 is due to the vendor per day.

Hope this solution will helpful to you and thank you dear student for being concerned 🙂

See less## A taxi driver filled his car petrol tank with 40 litres of petrol on Monday. the next day, he filled the tank with 50 litres of petrol. if the petrol costs 44 per litre, how much did he spend in all on petrol

Dear student we can solve this problem in this way : - The cost of petrol is 44 per litre. Expenditure on 40 litres of petrol on Monday is = 44 X 40 And expenditure on 50 litres of petrol on Tuesday is = 50 X 44 Therefore, the total money he spent = 44 × 40 + 50 × 44 = 44 (40 + 50) (Distributivity oRead more

Dear student we can solve this problem in this way : –

The cost of petrol is 44 per litre.

Expenditure on 40 litres of petrol on Monday is = 44 X 40

And expenditure on 50 litres of petrol on Tuesday is = 50 X 44

Therefore, the total money he spent

= 44 × 40 + 50 × 44 = 44 (40 + 50) (Distributivity of multiplication over addition)

= 44 × 90

= 3960

∴ He spent Rs. 3960 in all on petrol.

Hope this solution helps you to dispel all your doubts about this question 🙂

See less## Find the product of 1005 × 168

Dear student the solution to your question is here - 1005 × 168 1005 × 168 = 168 × 1005 (Commutativity) 168 × (1000 + 5) = 168 × 1000 + 168 × 5 (Using distributitivity) = 168000 + 840 = 168840 Hope you understand and thank you dear student for being concerned :)

Dear student the solution to your question is here –

1005 × 168

1005 × 168

= 168 × 1005 (Commutativity)

168 × (1000 + 5) = 168 × 1000 + 168 × 5 (Using distributitivity)

= 168000 + 840

= 168840
