Maggie buys 1 1/8 pounds of pecans, 9 ounces of almonds, and 5/8 pound of walnuts. How much do the nuts weigh in all?

The nuts weigth is 37/16 or 2.3125 pounds.

Step-by-step explanation:

In order to solve this problem we first need to convert all the measurements to the same unit, in this case we will convert ounces to pounds, to do that we need to divide the value by 16, we have:

almonds = 9/16 pounds

We can now convert the weigh of pecans from a mixed fraction to a simple fraction, to do that we sum the integer part to the fraction, we have:

pecans = 1 + 1/8 = 8/8 + 1/8 = 9/8 pounds

We now sum all the weigths:

total weigth = 9/8 + 5/8 + 9/16

Applying LMC we have:

total weigth = (2*9 + 2*5 + 9) / 16 = (18 + 10 + 9) / 16 = 37/16 = 2.3125 pounds

The nuts weigth is 37/16 or 2.3125 pounds.
