for instance,
1/4 + 3/5
or
2/5+ 6
1.5+ 2/5
etc.etc.etc.

you need to change decimals to fractions, mixed fractions to improper fractions.
ex.
1/4 + 3/5
in this case you should get the lcd. (20)
then, then divide 4 by 20 then multiply by 1
then, divide 5 by 20 and multiply by 3
5/20+12/20 then you can add now
17/20
in the second one, 1.5+ 2/5
change 1.5 to fraction that is 1 1/2 or 3/2
3/2 +2/5
the lcd is 10
10 divided by 2 times 3 is 15
10 divided by 5 times 2 is 4
15/10+4/10
19/10 or 1 9/10
