Let x be the height of the tree.
 
     1.3        x
   ------- =  ------
     1.8        7
 
     1.8x = (1.3) (7)
   
     1.8x /1.8 =  9.1 / 1.8  (divide both sides of equation by 1.8)
   
      x  =  5.1 meters

ANSWER:  The tree is 5.1 meters tall.

For black 1/12= 8%

Step-by-step explanation:

All you have to do is add up all the marbles 3 + 6 + 2 + 1 = 12 and then you put the number of marbles for each color and divide it by 12 which gives you those percentages. I don't know if you wanted the answers in percentages or fractions so I gave you both . Good luck!!
