Answer 1

We need 134 cups of pecans per pie. From the nutrition Facts, we know that 1 cup is about 99 g

The total weight of 134 cups of pecans is

grams

134 x 99 = 13266

We need to make 6 pies and each pie needs 134 cups of pecans. The total weight of pecans needed to make 6 pies is

grams

13266 x 6 = 79596

Finally, we need to convert the grams to pounds.

We know that 1 pound = 453.592 grams

(or we can use 1 pound = 16 ounces and 1 ounce = 28.35 grams to get 1 pound= 28.35*16=453.6 grams)

We will divide 79596 by 453.6 to get the weight in pounds

Weight of pecans = 79596 453.6 = 175.5

ans: You will need to buy 175.5 pounds of pecans

Alternatively, we can

start with finding how many pecans are in a pound,

We know that 1 cup weight 99 g and 1 pound = 453.592 grams

Number of cups in 1 pound is

453.592 number of cups/pound = = -= 4.5817 99

1 pound has 4.5817 cups of pecans.

We need 134 cups per pie. The weight of the pecans needed per pie is

pounds

134 4.5817

The total weight of pecans needed for 6 pies is

134 X 6 = 175.48

ans: You will need to buy 175.5 pounds of pecans
