If there are 20 red marbles and 40 blue marbles, the ratio of red to blue is 1 over 2. The number of white marbles does not matter.
Set up the problem as: y=number of yellow marbles & 4y=number of blue marbles. 40=y+4y or 40=5y or y=8. Therefore number of blue marbles is 4*8 = 32.

The southeast quarter of a section is 160 acres, and the southeast quarter of that is 40 acres. So, the southeast quarter of the southeast quarter of a section is 40 acres.
Let ( x ) be the number of red marbles to be added. Initially, there are 10 red marbles and 30 green marbles, making a total of 40 marbles. After adding ( x ) red marbles, the total number of marbles will be ( 40 + x ), and the number of red marbles will be ( 10 + x ). To find ( x ), we set up the equation: [ \frac{10 + x}{40 + x} = 0.6 ] Solving this equation gives ( x = 20 ). Therefore, 20 red marbles must be added to have 60% red marbles in the jar.
40 is a quarter of 160
