Where is the model. To answer I need the model.
Let the first digit of the 2-digit number be x and the second digit be y.
Then the ratio (x/y) equals (1/2). Write a formula for y in terms of x.
The tens digit is 2 more than the units digit. Using the letters x and y, write out the proper equation.
Now solve your two equations simultaneously for x and y.

Answer:
4/11
Step-by-step explanation:
There are 11 marbles in total, if 4 of them are white, then you have a 4/11 chance of getting a white marble.
Well, the chances are 3 to 1 in the first question, because there are three pencils and only one pen. In the second box it is a 50-50 chance that you will pick a crayon, because there are equal amounts of colored pencils and crayons in the second box. The numbers that I gave you aren't the fractions though. See if you can go from here.
