team of scientists found that there were 4 oak trees for every 10 pine trees. How many oak trees were there if they counted 36 more pine than oak?

John
One method is to use equivalent fractions until you find a difference of 36.
For instance 4/10 = 8/20 and the difference between 20 and 8 is 12.
4/10=12/30 and the difference between 30 and 12 is 18.
4/10=16/40 and the difference is 24... etc
