Question

What number is midway between 2/5 and 1?

Answer 1

4/10 and 10/10:

7/10.

Answer 2

Answer:
`(7)/(10)`

Explanation:

To find the mid point 'c' between any two numbers 'a' and 'b' we apply the following rule:-

`c=(a+b)/(2)`

Now, the number is midway between 2/5 and 1 will be given by :-

`\c=((2)/(5)+1)/(2)\\\\\Rightarrow\ c=((7)/(5))/(2)....\text{[by taking LCM]}\\\\\Rightarrow\ c=(7)/(2*5)\\\\\Rightarrow\ c=(7)/(10)`

Hence, the number is midway between 2/5 and 1 =
`(7)/(10)`
