I'm doing my math, but i don't understand these 3 things mean: lowest common denominator simplest form of a fraction reciprocal help plz and thank u!

When adding fractions like 1/3 and 3/5, the Lowest Common Denominator is the smallest number that is a integer-multiple of both 3 and 5. In this case it would be 15. You would get the sum by adding 5/15 and 9/15 to get 14/15. The simplest from of a fraction is the form in ...

lowest common denominator is (x-9)(x+9)(x+3) (2(x+9) - (x-9))/lcd or (x+27)/LCD

Are you sure that is correct? Because I came up with this. 1. Write problem using positive exponents 2. Find the Least Common Denominator 3. Multiply the numerator and denominator by the LCD (xy) 4. Apply Distributive Property 5. Simplify

32 = 2^5 75 = 3x5x5 LCM (or same as lowest common denominator) = (2^5)(3x5x5) = 32x75 = 2400 since the two numbers have no common factors between them you would just take their product. however, for something like 12 and 36 ... 12 = 4x3 40 = 4x2x5 so LCM = 4x3x2x5 = 120

no, subbing it in would show you that it does not work. hint: x/[5(x+2)] + (x-3)/(x+2) = 7/5 isn't the lowest common denominator 5(x+2) ? multiply each term by that

x^3 + y^3 = (x + y)(x2 - xy + y2) The lowest common denominator is therefore x^3 + y^3. (x+y) is a factor of both denominators x/(x+y) = [x(x^2 -xy + y^2)]/(x^3 + y^3)

Find the least common denominator (LCD) for fractions with the given denominators. 1/3 + 5/12 + 4/5

When you're adding or subtracting fractions, you need to find the least common denominator. For instance: 1/2 + 3/4 + 5/8 = 4/8 + 6/8 + 5/8 = 15/8 The least common denominator is also the least common multiple. In the above problem that is 8.

in that case just multiply each term by 9, the lowest common denominator to get 4n + 54 = 12 I am sure you can take it from there.

i thought i was adding...i do not understand what u are saying about 60? above the fractions i wrote this is what it says... Find the least common denominator (LCD) for fractions with the given denominators not the multiply..sorry

Find the least common denominator (LCD) for fractions with the given denominators 13/15 - 11/20=2/5?

Correct! And you have found correctly the lowest common denominator.

start by multiplying by the lowest common denominator (in this case 4), simplify, then solve. 4(x/2) + 4(x/4)= 1 4/2=2 and 4/4 =1, therefore: 2x + x = 1 3x = 1 (3x)/3 = 1/3 x= 1/3

All of them appear to me to be molecular formulas. The empirical formula of ribose is CH2O and for ethyl butyrate it is C3H6O. C and D don't appear to have a lowest common denominator other than 1. Check my thinking.

You need to find the least common denominator to do this. http://www.aaastudy.com/fra.htm Click on Divisibility Rules... and then on Least Common Denominator.
