Goivanna france and their dad each carried 10-pound bag of soil into the backyard after putting soil in the flower bed givenna bag was 5/8 full how many ounces of soil did goivenna use

Goivanna's bag was 10 pounds. There are 16 ounces in a pound, so she had 10 x 16 = 160 ounces in her bag to start with.

If she has 5/8 of the bag left, then you know she used 3/8 of her bag (the whole bag [8/8] - what she had left [5/8] equals what she used [3/8]).

If she used 3/8 of the bag, you do 160 x 3/8 which gives you 60 ounces that she used.
