Sahana has only blue and yellow fish in her aquarium. If 25% of the fish are yellow, what is the ratio of the number of BLUE fish to that of YELLOW fish? Help

you says that 25%. it's mean yellow fish 1/4 of total

and blue fish 75%. means 3/4

So, the ratio of blue yellow be 3:1

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
