1. first find the common dinominator = 20

then get the fraction worked out

12 3/4 = 12 15/20

6 9/10 = 6 18/20

then just add it

12 + 6 = 18

15/20 + 18/20 = 33/20 = 1 13/20, add this to the total

18 + 1 13/20

=19 13/20

2. if the top level is 100 mre than the bottom (-45) then just add

100 + (-45) = whish is basically subtraction = 100-45 = 55, if u need more h ekp in any problems notify me, i am a math tutor, ill be happy to help you

The second answer is 55 feet. The first is something like this:

12 3/4 + 6 9/10

12 15/20 + 6 18/20

19 13/20

Hope you make a n A!

1.-51/4 + 69/10 = -255/20 + 138/20

= 117/20 = 5 17/20

2. -45 + 100 = 55ft
