Answer 1

Total weight of three items is 2.875 pounds

Solution:

Given that,

Maya is packing her backpack for hike

From given,

`pound\ bag\ of\ trail\ mix = (1)/(2)\ pounds`

`water\ bottle = 2(1)/(8)\ pounds = (17)/(8)\ pounds\\\\flashlight = (1)/(4)\ pounds`

How much weight do these three items add to her backpack?

Add all these together

`Total\ weight = (1)/(2) + (17)/(8) + (1)/(4)\\\\Total\ weight = (1 * 4)/(2 * 4) + (17)/(8) + (1 * 2)/(4 * 2)\\\\Total\ weight = (4)/(8) + (17)/(8) + (2)/(8)\\\\Total\ weight = (23)/(8) = 2.875`

Thus total weight of three items is 2.875 pounds
