What is the process to find the total amount of food a bunny eats over a period of days if it eats a fraction of an ounce each day?

Back

To find the total amount of food, multiply the daily amount by the number of days. For example, if a bunny eats 1/2 ounce per day for 6 days, the calculation is (1/2) * 6 = 3 ounces.

How do you determine the fraction of students present in a class?

Back

To find the fraction of students present, subtract the number of absent students from the total number of students, then divide by the total number of students. For example, if there are 27 students and 10 are absent, the fraction present is (27-10)/27 = 17/27.

How do you simplify a fraction?

Back

To simplify a fraction, divide both the numerator and the denominator by their greatest common divisor (GCD). For example, to simplify 4/8, divide both by 4 to get 1/2.

What is the difference between a proper fraction and an improper fraction?

Back

A proper fraction has a numerator smaller than the denominator (e.g., 3/4), while an improper fraction has a numerator larger than or equal to the denominator (e.g., 5/4 or 4/4).
