7 pounds = 16 pounds and 1 pound = 6 pounds and 16 ounces.
(6 pounds + 16 ounces) minus (5 pounds + 10 ounces) = 1 pound + 6 ounces
*** ** *(6pounds+16ounces)-(5pounds+10ounces)=1pounds +6ounces
You need 22 more ounces of laundry to make a full load in the washer. The washer's capacity is 112 ounces, while your current laundry weighs 90 ounces. Therefore, 112 ounces minus 90 ounces equals 22 ounces needed.
