I hope it's this??? but I'm not sure
The answer is 3.33%. Anna reduced her CO2 emissions by 3.33% from using 600 gallons of gas annually than from using 900 gallons of gasoline annually. I arrived to this answer through multiplying gallons by 20 pounds of C02 (600*20) = 12000; (900*20) = 18000. Then I proceeded to subtract 12000 from 18000 which yielded me 600 (18000-12000 = 600). Lastly, I divided 600 by 18000 and it gave an answer of .0333. Then, I converted it to percent, thus, yielding me the answer of 3.33%.
10*0.2=2 When you are multiplying a decimal by 10 you just take off the decimal and you have the answer 2
Answer:
5/6−1/9=13/18
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(5/6×3/3)−(1/9×2/2)=?
Complete the multiplication and the equation becomes
15/18−2/18=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
15−2/18=13/18
This fraction cannot be reduced.
Therefore:
5/6−1/9=13/18
1/4 exact form, 0.25 decimal form.
