Question

kylie bought a bunch of grapes that weighs 2 pounds and 9 ounces. How much did the grapes weigh in ounces only?

Answer 1

Since 1 pound is 16 ounces, you would convert the 2 pounds to 32 ounces (16+16) and add the 32 ounces to the already given 9 ounces to get 41 ounces. (32+9)
Hope that helped.
