Why do you need to find the number that is half way between zero and 1 1/2

3/4

Step-by-step explanation:

That sounds like a good and interesting question.  The key here is to learn and know how to find the number halfway between 0 and 1 1/2.

In other words, find the number halfway between 0 and 3/2.  Half of the distance between these two numbers is 3/4.  This is the desired number.

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
