A. Find out what you have to do to get from 15 to 20. You multiplied 15 by 1 and 1/3. Do the same for the numerator. So multiply 6 by 1 and 1/3 to get 8. The answer is 8/20. Hope this helps:)

What fraction of the original air must be removed?
Q. A tire is filled with air at 15*C to a gauge pressure of 250 kPa. If the tire reaches a temperature of 38*C, what fraction of the original air must be removed is the original pressure of 250 kPa is to be maintained?

A. The general law of gases is: PV=nRT In this case where both the volume and the pressure are kept constants the general law reduces to: nT=constant then: n1*T1=n2*T2 then: n1/n2=T2/T1 then: n2=n1*(T1/T2) then the fraction to be removed from the original amount of air is: (n1-n2)/n1 =(n1-(n1*(T1/T2))/n1 =n1(1-(T1/T2))/n1 "common factor extracted This implies that the fraction to be removed from the original amount of gas equals: 1-(T1/T2)=1-(288/311)=app roximately 7.4% from the original amount note: the fraction to be removed is the same if we are talking about the mass of gas to be removed or its molar number.

What fraction of the total kinetic energy is the rotational kinetic energy of the wheels on a bike?
Q. A bicycle has wheels of radius 0.23 m. Each wheel has a rotational inertia of 0.093 kg m2 about its axle. The total mass of the bicycle including the wheels and the rider is 72 kg. When coasting at constant speed, what fraction of the total kinetic energy of the bicycle (including rider) is the rotational kinetic energy of the wheels?
Asked by Ari - Wed Oct 28 16:00:35 2009 - - 2 Answers - 0 Comments
A. The TOTAL kinetic energy is the sum of translational AND rotational kinetic energy. So (after much substitution, rearrangment and cancellation) %rot = (2*I/r**2) / ( 2*I/r**2 + m) where: I = mass moment of inertia for the wheels = .093 kg*m**2 r = radius of wheels = .23 m m = total mass of cycle and rider = 72 kg %rot = [2*.093/.23**2] / { [2*.093/.23**2] + 72 }*100 = (3.52)/(3.52 + 72) *100 = 4.66 %

Why does multiplying a fraction by its conjugate not change its value?
Q. I came across this technique when dividing complex/imaginary numbers. When you use the technique on those numbers, it actually simplifies them. I tried using the technique on regular fractions and noticed that it does not change the original fraction. I'm going to assume it doesn't change the value of the complex fractions either, but somehow "re-phrases" them.
Asked by Stephen Riach - Sun Jan 18 12:56:07 2009 - - 2 Answers - 0 Comments
A. You are NOT multiplying the "fraction by its conjugate". You are multiplying BOTH the top and the bottom of the fraction by the same complex number. That is equivalent to multiplying the fraction by 1, which does not change its value. For example, if you want to simplify (3+2i) / (4+3i) you would multiply both top and bottom by (4-3i). This is the same as multiplying the fraction by (4-3i) / (4-3i) = 1. The reason this simplifies the fraction is that when you multiply a complex number by its conjugate the imaginary parts cancel out leaving you with a real number. So, you end up with a real number on the bottom of the fraction, which you can distribute to the two parts of the top.

Asked by London-England- - Sun Oct 22 14:16:56 2006 - - 9 Answers - 0 Comments
A. to convert a fraction into a decimal, divide the numerator by the denominator and do long division until you get a remainer of zero: let's say you're converting 3/4 into a decimal. Thus you are dividing 4 into 3, since this isn't possible add a 0 and place a decimal into your answer. Thus 30/4 = 7 with a remainder of 2. Add a 0 and divide again. 20/4 = 5. Therefore, your decimal is 0.75 To convert a decimal into a percent, multiply the decimal by 100. Thus, 0.75 = 75% Hope this helps

A. x = numerator x + 36 = denominator So the fraction is x/(x + 36) Now add 1 as stated to the numerator... x + 1 Now add 5 to the denominator as stated... x + 36 + 5 This becomes (x + 1)/(x + 36 + 5) (x + 1)/(x + 36 + 5) = (x + 1)/(x + 41) The question says when we add 1 to the numerator and 5 to the denominator the fraction becomes 5/8 so: (x + 1)/(x + 41) = 5/8 I am using "cross multiply" to solve: 8(x + 1) = 3(x + 41) 8x + 8 = 3x + 123 Gather alike terms to either side: 8x - 3x + 8 - 8 = 3x - 3x + 123 - 8 (add a -8 and -3x to each side) 5x = 115 Divide both sides by 5 to solve for x: 5x/5 = 115/5 x = 23 x + 36 = 59 So the original fraction is: 23/59

A. Firstly find common denominator (the denominator is the bottom number). In this question the common denominator is 12. Just in case :) The common denominator is the number that is a factor of both denominators. A way to find this is to list the factors. factors of 4: 4 , 8 , (12) , 16 , 20 factors of 3: 3 , 6 , 9 , (12) , 15 , so if the common denominator is 12, then you have to change 4 and the 3 to 12 by multiplying them up, 4 x 3 = 12 3 x 4 = 12 Remember, what you do to the bottom you have to do to the top. so if you had: (common denominator = 12 ) 3 1 3 1 -- + -- which equals -- + -- Multiply to equal 12 ---> 4x3 3x4 12 12 then multiply the Numerator by the same amount ---> 3x3 1x4 9 … [cont.]

A. 6 goes in to 41 6 times fully, that is your whole number. The difference between 36 and 41 is 5, that is your numerator. The denominator stays the same; 6. The answer is 6 5/6.

How do you work an equality equation with a fraction?
Q. I 'm comfortable working equalities with only whole numbers, but have forgotten how to do it when it involves a fraction. Example 2/5r - 4 = -2 What is the process for this equation? Thanks for your help!
Asked by D M - Mon Mar 16 22:03:17 2009 - - 2 Answers - 0 Comments
A. i would multiply everything by 5 to clear out the denominator so it would be 2r-20=-10 adn then solve that so r=15
