Karla bought 2 pounds of red beads , 1 3/4 pounds of green beads , and 10 ounces of string at the craft store. how much do karla's supplies weigh in all.

First you can change the mixed fraction (1 3/4) into an improper fraction.  First you add the whole number add the nominator and then multiply what you get by the denominator.  So 1+3=4, 4x4=16.  Then we have 16/4 which simplifies to 4.  Now we can add everything else because they all have common denominators (2/1, 4/1, 10/1).  So 2+4=6.  6+10= 16.
The final answer is 16 pounds.
