Question

1. add negative fraction with positive fraction

-7/8 + 1/4 = ?

2. add negative decimal with positive decimal
-12/5 + 15.3 = ?

Answer 1

Given parameters:

1.
`-(7)/(8) + (1)/(4)`

`-(7)/(8) + (1)/(4)`; find the LCM = 8

=
`(-7 + 2 )/(8)`

=
`(-5)/(8)`

2.
`-(12)/(5) + 15.3`

Make the fraction decimal;

`-(12)/(5)` = -2.4

So;

-2.4 + 15.3 = 12.9
