Carla bought two pounds of red beads 1 3/4 pounds of green beans and 10 ounces of string at the craft store how much do carla supplies weigh in all

70 ounces or 4.375 Pounds. (They weigh the same)

Explanation:
First off all, lets convert everything to improper fractions. Two pounds converted into a fraction would be 2/1. 1 3/4 would be 7/4. After converting the fractions of pounds, we add them. 2/1 + 7/4. Since they have different denominators, we have to find the Lowest Common Multiple which would be 4. Leave the right side alone  and multiply 4 to your left denominator and numerator.  That would leave you with 8/4 + 7/4. Adding them up, you would get 15/4. Divide that, and you should get 3 3/4 Pounds. Convert that into ounces. (16 ounces = 1 Pound) and you should get 60 ounces. Add the 10 ounces from the sentence and you should get 70 ounces
