Chapter 3 — Calculating Measurements A fraction represents part of a whole. The numerator represents the part and the denominator represents the whole.

Chapter 3 — Calculating Measurements Improper fractions can be converted into mixed numbers and mixed numbers can be converted into improper fractions.

Chapter 3 — Calculating Measurements When all the fractions in a calculation involving addition or subtraction have a common denominator, the numerators are added or subtracted and the denominator stays the same.

Chapter 3 — Calculating Measurements Before fractions with unlike denominators can be added or subtracted, a lowest common denominator must be determined.

Chapter 3 — Calculating Measurements Fractions with unlike denominators must be rewritten as fractions of equivalent value with common denominators before they can be added together.

Chapter 3 — Calculating Measurements Fractions with unlike denominators must be rewritten as fractions of equivalent value with common denominators before they can be subtracted.

Chapter 3 — Calculating Measurements When multiplying fractions, the numerators are multiplied by each other and the denominators are multiplied by each other.

Chapter 3 — Calculating Measurements Dividing fractions requires converting the divisor fraction into its reciprocal.

Chapter 3 — Calculating Measurements In a decimal, whole numbers are located to the left of the decimal point and the decimal part is located to the right of the decimal point.

Chapter 3 — Calculating Measurements Decimals are rounded up or down depending on the value of the last digit in the decimal.

Chapter 3 — Calculating Measurements Decimals are added and subtracted in the same way as whole numbers.

Chapter 3 — Calculating Measurements When multiplying decimals, the location of the decimal point in the product is based on the number of decimal places in the decimals being multiplied.

Chapter 3 — Calculating Measurements When the divisor and dividend in a division calculation are both multiplied by the same factor of 10, the value of the quotient does not change.

Chapter 3 — Calculating Measurements To convert a fraction to a decimal, divide the numerator by the denominator.

Chapter 3 — Calculating Measurements Any decimal can be converted to a fraction by setting the denominator as a power of 10.

Chapter 3 — Calculating Measurements The area of a rectangle is equal to length × width and is expressed in square units of measure.

Chapter 3 — Calculating Measurements The radius of a circle is equal to one half the diameter of a circle.

Chapter 3 — Calculating Measurements When a circle is divided into equal portions through the center, central angles are created that equal the number of degrees that the portion of the circle contains.

Chapter 3 — Calculating Measurements Angles can be used in recipe instructions to explain how to hold kitchen equipment when performing different tasks.
