Answer 1

Working out:

8) a. Here we are given with a question which is aksing for the least number to be multiplied with an odd number to get an even number.

First of all we know that, Even number is a number which is divisible by 2 or completely divides 2 with remainder 0. And Odd number is vice versa. So, for making an odd number an even number, of course we need to multiply it with 2 or any of its multiple.

But we need the least number:

• Least number to be multiplied = $\boxed{2}$

b. Given number = 650

This can be written as 65 × 10

Further, 65 can't be divided anymore with 2 as we need 2 because for getting 10, we need 2 and a 5.

• 10 = 2 × 5

So, if we multiply 10, 65 times we will get 650 because 10 × 65 gives 650.

• No. of tens in 650 = $\boxed{65}$

And we are done !!

Answer 2

Answer:

8. (a) What is the least number to be multiplied with an odd number to make it an even number ?

$\mapsto$ The least number to be multiplied with an odd number to make it an even number is 2 because even number is a number that can only divisible by 2.

$\therefore$ So the least number will be 2.

(b) How many tens are there in 650 ?

$\mapsto$ There are 65 tens in 650 because there are 65 × 10 so tens place are left over and 65 is remaining .

$\therefore$ No of tens in 650 is 65.
