A few years ago, a country consumed 19,400,000 barrels of oil per day. That same year, there were about 119,000,000 households i
n that country. A barrel of oil is 42 U.S. gallons. Estimate how many gallons each household in the country consumed each day that year by rounding down all three numbers. (Round 19,400,000 barrels to 19,000,000 barrels, 119,000,000 households to 115,000,000 households, and 42 gallons to 40 gallons. Round your answer to two decimal places.) _________ gal/household/day
Calculate the answer without using estimation and compare the two results. (Round your answer to two decimal places.)
___________gal/household/day
To divide a fraction by a fraction, you multiply the first fraction by the reciprocal (aka the fraction flipped upside down, in this case the reciprocal of 5/6 is 6/5). Since 6/5 is greater than 5/6, 3/8 divided by 5/6 is greater than 3/8 times 5/6.
