Question

What should be added to -13/25+21/5+-21/18 to get 5?​

Answer 1

ATQ,

=
`( - 13)/(25) + (21)/(5) + ( - 21)/(18) + x = 5`

• Take the lcm of 25,5,18 and then manipulate it accordingly.

=
`( 377)/(150) + x = 5`

=
`x = 5 - ( 377)/(150)`

=
`x = ( 373)/(150)`

Answer 2

=727/150

Explanation:

-13/25 + 21/18 + 21/18

= -13 + 105/25 + 21/18

= 92/25 + 21/18

= 1656 + 525/450

= 2181/450 = 727/150
