<span>The Least Common Multiple (LCM) of a group of numbers is the smallest number that is a multiple of all the numbers. For instance, the LCM of 16 and 20 is 80; 80 is the smallest number that is both a multiple of 16 and a multiple of 20. You can find the LCM of two or more numbers through various methods. If you would like to know how to find the LCM of two or more numbers,</span>
(-2/3)*(-2 1/4)*(3/4) Convert the mixed fraction to improper fraction.
(-2/3)*(-9/4)*(3/4) Then you multiply the numerators with numerators and denominators with denominators
(-2*-9*3) negative times negative is positive, so the negative sign is gone
-------------
(3*4*4*) The lines (-----) is the line of the fraction
54/48 This is the product of this multiplication, now you need to simplify
by reducing the numbers of the fraction
9/8 And that would be the answer
1)
-2(3x+4)=-6x-8≠-6x+8
2)
2(-3x+4)=-6x+8
3)
5(x+1)-11x+3=5x+5-11x+3=-6x+8
4)
x+2-7x+6=-6x+8
5)
8-6x=-6x+8
Answer: The expressions 2,3,4 and 5 are equivalents.
