For every 1 litre of water used to make a medicine, 400 ml of sucrose and 300 ml of saline solution are used. express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.

10 : 4 : 3

Step-by-step explanation:

According to the question,

For a medicine,

Water used = 1 liter = 1000 ml

Sucrose used = 400 ml

And, Saline used = 300 ml

Thus, the ratio of water, sucrose and saline water for making a medicine,

= 1000 : 400 : 300

= 10 : 4 : 3

Which is the required simplest form of the ratio of water, sucrose and saline water.

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
