I have another one and I am having the same arguement with my friend.
I say these have to be turned into inproper fractions before adding am I correct?
Yes, you are correct.
5+%284%2F5%29+%2B+4+%285%2F6%29+%2B+1+%283%2F10%29
= 29%2F5+%2B+29%2F6+%2B+13%2F10....now find LCD.....it is 30
=6%2829%2F30%29+%2B+5%2829%2F30%29+%2B+3+%2813%2F30%29
=%286%2A29%29%2F30%29+%2B+%285%2A29%29%2F30%29+%2B+%283%2A13%29%2F30%29
=%28174%29%2F30%29+%2B+%28145%29%2F30%29+%2B+%2839%29%2F30%29
=358%2F30
