Answer:
0.236
Step-by-step explanation:
First put it in order
0.199, 0.211, 0.225, 0.236, 0.257, 0.264, and 0.283
Then find the middle number
0.236
2 is 2/3 of 3. So 3 times 2/3 is 3. And 3 is a ratio to 2(cups of solvent). Using that logic we can find 2/3 of the cups of solvent. 2 times 2/3 is 4/3. Thus, he would need 4/3 cups of solvent.
