In basketball, some baskets are worth two points. others are worth three points. in one game, the ratios of three-point baskets to three-point tries for one team was 3 : 4. if the team scored 27 points from three-points baskets, how many three-point baskets, how many three-point tries did the team have?

Writing the information in form of ratio

Three point basket: Three point tries
            3                  :           4
           27                 :           x

Think about multiplication, how many 3s do you need to make 27? 
It's 27 ÷ 3 = 9

Because you need 9 lots of 3, then to make it proportional, you'd need 9 lots of 4 

9 × 4 = 36

Three-points tries is 36 points

The last one hope it works
