Question

18 2by5-4 1by10 find the difference

Answer 1

Given:

The expression is:

`18(2)/(5)-4(1)/(10)`

To find:

The difference.

Solution:

We have,

`18(2)/(5)-4(1)/(10)`

It can be rewritten as:

`=(90+2)/(5)-(40+1)/(10)`

`=(92)/(5)-(41)/(10)`

Taking LCM, we get

`=(184-41)/(10)`

`=(143)/(10)`

`=(140+3)/(10)`

`=14(3)/(10)`

Therefore, the value of the difference is
`14(3)/(10)`.
