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.

What is the method to add two large numbers together?

Back

To add large numbers, align them by place value (units, tens, hundreds, etc.) and add each column starting from the right, carrying over if necessary. For example, to add 85,690 and 990, align them and add to get 86,680.

How do you multiply two numbers together?

Back

To multiply two numbers, you can use the standard algorithm: multiply each digit of the first number by each digit of the second number, and then add the results together. For example, 85 x 80 = 4,250.

What does the value of a digit in a number represent?

Back

The value of a digit in a number is determined by its position. For example, in the number 569,867, the 5 is in the hundred-thousands place, so its value is 500,000.

What is a fraction and how is it represented?

Back

A fraction represents a part of a whole and is written as two numbers separated by a slash, such as a/b, where 'a' is the numerator (part) and 'b' is the denominator (whole).

How can you convert a fraction to a decimal?

Back

To convert a fraction to a decimal, divide the numerator by the denominator. For example, 1/2 = 0.5.

What is the importance of understanding place value in mathematics?

Back

Understanding place value is crucial because it helps in reading, writing, and performing operations with numbers accurately. It determines the value of each digit based on its position.

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).
