Va rog sa ma ajutați: 420/180x54/180

First, you want to divide 420 by 180. Then, divide 54 by 180. Lastly, you want to multiply the answers of the two together.
                    - 
420/180= 2.3 

54/180= 0.3

2.3 * 0.3 = 0.69

*You just take it step by step. Hope I helped. :)

Start by simplifying the fractions, its usually easier to leave it as a top heavy fraction. So we would do 420/180 which can be simplified to 7/3 (we can divide both the top and botton of the fraction by 60)
Then we can do 54/180 which is 3/10.
Now we have some nicer fractions all we have to do is multiply 7/3 x 3/10. To do this we can just multiply the tops and bottoms of the fractions so we get 21/30. This can be simplified one last time to get a final answer of 7/10 or 0.7

Iwould say this is false, because the mean and median are similar, though the mode is way different. but it might be true depending how you like at it. sorry if i'm being confusing : )
