Hii! I need help with this question! The question is "You have 8 hours to get ready and 5 1/2 of those hours have already passed. How much time do you have left?" Someone help ASAP!

2 1/2 hours

Step-by-step explanation:

3 1/2 hours left

Step-by-step explanation:

Write an equation for this:

8 - 5 1/2 = how much time you have left

(8 is the total hours, you subtract since the hours passed, and 5 1/2 is the amount of hours passed)

Solve equation:

8 - 5 = 3, add the 1/2

So, 8 - 5 1/2 = 3 1/2 or 3.5

b, i believe, but not sure.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
