18 2by5-4 1by10 find the difference

luda_lava [24]

Given:

The expression is:

$18\dfrac{2}{5}-4\dfrac{1}{10}$

To find:

The difference.

Solution:

We have,

$18\dfrac{2}{5}-4\dfrac{1}{10}$

It can be rewritten as:

$=\dfrac{90+2}{5}-\dfrac{40+1}{10}$

$=\dfrac{92}{5}-\dfrac{41}{10}$

Taking LCM, we get

$=\dfrac{184-41}{10}$

$=\dfrac{143}{10}$

$=\dfrac{140+3}{10}$

$=14\dfrac{3}{10}$

Therefore, the value of the difference is $14\dfrac{3}{10}$ .
