Quick question on algebra?

[From: ] [author: ] [Date: 14-01-15] [Hit: ]
Lets say if the problem is 2x/(3/2) and you want to simplify it, I know you can do 2/3 * 2x = 4x/3 but I dont really understand the whole reciprocal process like,2x/(3/2) so you multiply it by 2/3 but shouldnt that cancel out the 3 and 2 and not make 2 * 2x/3?This is like multiplying by 1 .it does. You multiply the numerator and denominator by 2/3.......
Hey, I have a quick question on reciprocals.

Lets say if the problem is 2x/(3/2) and you want to simplify it, I know you can do 2/3 * 2x = 4x/3 but I don't really understand the whole reciprocal process like,

2x/(3/2) so you multiply it by 2/3 but shouldn't that cancel out the 3 and 2 and not make 2 * 2x/3?

Numerator = 2x

Denominator = 3/2

NOW MULTIPLY BOTH NUMERATOR AND DENOMINATOR BY 2/3

This is like multiplying by 1 . No change in value

Numerator = 2x X 2/3 = 4x/3

Denominator = 3/2 X 2/3 = 1

ANSWER 4x /3

-
it does. You multiply the numerator and denominator by 2/3. 2/3*3/2=1 in the denominator which is what you wanted
then you multiply the numerator by 2/3 to get 4x/3
hope you understand
