What is a fraction?

Back

A fraction represents a part of a whole and is expressed as a ratio of two numbers, the numerator (top number) and the denominator (bottom number). For example, 1/2 means one part out of two equal parts.

How do you add fractions with different denominators?

Back

To add fractions with different denominators, first find a common denominator, convert the fractions to equivalent fractions with that denominator, and then add the numerators. For example, to add 1/4 and 1/3, the common denominator is 12: (1/4 = 3/12) + (1/3 = 4/12) = 7/12.

What is the process to divide a fraction by a whole number?

Back

To divide a fraction by a whole number, multiply the denominator of the fraction by the whole number. For example, to divide 3/4 by 2, calculate 3/(4*2) = 3/8.

What is a mixed number?

Back

A mixed number is a whole number combined with a fraction. For example, 2 1/2 is a mixed number, which means 2 whole parts and 1/2 of another part.

How do you convert a mixed number to an improper fraction?

Back

To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator. Place this result over the original denominator. For example, 2 1/2 = (2*2 + 1)/2 = 5/2.

What is the formula for finding the total number of servings from a total amount?

Back

The formula is: Total Amount ÷ Serving Size = Total Servings. For example, if you have 42 1/2 ounces and each serving is 1 1/4 ounces, you would calculate 42.5 ÷ 1.25 = 34 servings.

What does it mean to have a negative result in a calculation?

Back

A negative result in a calculation indicates that the quantity being measured is insufficient or that there is a deficit. For example, if Greg's calculation resulted in -14 1/2, it means he does not have enough paper.

How do you multiply a fraction by a whole number?

Back

To multiply a fraction by a whole number, multiply the numerator by the whole number and keep the denominator the same. For example, 3/4 * 2 = 6/4 or 1 1/2.

What is the importance of understanding units in measurement?

Back

Understanding units in measurement is crucial because it ensures that calculations are accurate and meaningful. For example, mixing inches with feet without conversion can lead to incorrect results.

Front

What is a common denominator?

Back

A common denominator is a shared multiple of the denominators of two or more fractions, allowing them to be added or subtracted. For example, the common denominator of 1/4 and 1/3 is 12.
