Answer:
D. naturalistic observation
Step-by-step explanation:
Naturalistic observation is a method of research that consists in observing subjects in their natural environment without any exterior interferences that could alter their behavior. By posing as a student, Dr. Jimand is inserting himself among the other students to observe their natural behavior. For instance, if they were told that there was a doctor observing them, the students' behavior could change and that wouldn't be a true naturalistic observation.
<span>The
missing pieces strategy is another method to compare two fractions. To tell
which number is larger, you ned to see which one is missing less. For example
you have ¾ versus 4/5. Each of these fraction needs 1 to complete the whole. You
need to subtract the numerator with one to compare them. For ¾ we have ¼ and
for 4/5 we have 1/5. You know that if you complete 4/5 you will get 5 and for ¾
you will get 4. You know that 5 is greater than four. Therefore, 4/5 is larger
than ¾.</span>
