Answer:
<h2>
Amount of ounces of candy left = 22ounces</h2>
Step-by-step explanation:
Amount of halloween candy bought by Jack = 5pounds
Amount he gave trick = 3pounds
Amount jack ate = 10ounces
Before we can determine the amount of halloween candy that Jack has left, we need to convert the pounds to ounces in order to make the units consistent.
given 1pound = 16ounces
5pounds = 16* 5 ounces
5pounds = 80ounces
Also;
3pounds = 16*3 ounces
3pounds = 48ounces
Total amount of halloween used up by Jack = 48ounces + 10ounces
= 58ounces
Amount of ounces of candy left = Total amount of candy bought -amount used up
Amount of ounces of candy left = 80ounces - 58ounces
Amount of ounces of candy left = 22ounces
7 9/12 = 7.75
2 11/12 = 2.917
So we can round both of these up.
7.75 rounds to 8
2.917 rounds to 3
8 + 3 = 11
So the estimated sum is 11.
7 9/12 + 2 11/12 = 10 2/3
So the actual sum is 10 2/3.
The estimated sum is a pretty good estimate to the original number.
