Ricky completely filled a bucket to wash his car. After he finished washing the car, 5/8 of the car remained in the bucket. What fraction of the water they Ricky use? Use the number line to show how you find your answer

1-5/8=3/8

If he had 5/8 leftover, then he used 3/8.

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
