Well in order to solve this we need to find how many ounces are in 1 cup well ill just tell you:) according to google in one cup there is 7.99986 ounces so lets take that number and multiply it by three to get our 3 cups of pear puree 7.99986 x 3 = 23.99958 now we have our 3 cups in ounce form and since she has containers that are two ounces lets divide 23.99958 by 2 23.999÷2= 11.9995 so this means that she filled about 12 containers of frozen pear puree hope this is helpful:) MARK ME BRAINLIEST!:D
