Chelsea mailed 2 boxes and 2 bags to her uncle in army. The two boxes weighed 8 ½ pounds each and the two bags weighed 4 ½ pounds each. How many pounds do all 2 boxes and 2 bags weigh?

26

Step-by-step explanation:

4.5x2=9+17=26

8.5x2=17

26lbs.

Step-by-step explanation:

this problem is quite simple when we break it down

first we multiply each of the amounts of the bags and the boxes by two to represent the two of each items as shown

8 1/2 * 2 = 17

4 1/2 * 2 = 9

then all we have to do is add the two new amounts together and TADA:

17 + 9 = 26

we have our answer

NOTE: when multiplying a fraction, you are multiplying how many parts (the numerator) and NOT the size of the part within the whole number (the denominator) in this case 1/2 * 2 = 2/2 and 2/2 = 1
