How to solve 33/22 = 6/k cross products, common numerators/denominators, equivalent fractions and lcd

Help! How to solve this problem all 4 ways

33........6
***..=..***
22.......X

3..........6
**...=...**...............cross products
2.........X

3X = 12

X=4


3..........6
**...=...**...............common numer/denom
2.........X...............equivalent fractions same as common den/num

X*3..........2*6
*****...=...*****..............When the denominators are alike set the numerators equal
X*2..........2*X

3X = 12

X = 4

3..........6
**...=...**...............LCD
2.........X

3..........6
**...=...**...............Multiply thru by 2X
2.........X

2X*3.........2X*6
******...=...******
...2...............X

x*3 = 2*6

3X = 12

X = 4

33/22 divided by 11/11 is 3/2.

So, 3/2 = 6/k
Do cross multiplication, you get 3k = 12
k=4
