Answer:
27.8 per mile.
Step-by-step explanation:
417 divided by 15 equals 27.8 miles per gallon
miles/ gallon
/ = per
so
417/ 15
27.8 gallons
We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits. We then round the last digit. We fill in any remaining places to the right of the decimal point with zeros.
3 and 3/4lb=20.25
what you should do is divide both sides by 3 and 3/4 but that isnt nice
convert 3 and 3/4 to improper
3 and 3/4=3+3/4=12/4+3/4=15/4
15/4lb=20.25
times 4/15 to both sides (15/4 times 4/15=60/60=1)
1lb=81/15
1lb=5.4
answer is
1lb=$5.40
The exact volume would be 80 feet long
