Types of gravel include: 1  Bank gravel: naturally deposited gravel intermixed with sand or clay found in and next to rivers and streams. 2  Bench gravel: a bed of gravel located on the side of a valley above the present stream bottom, indicating the former location of the stream bed when it was at a higher level.
You can multiply the numerator and the denominator by 4, as shown in part B above. But you cannot multiply the numerator by 4 and the denominator by 2. The numerator and the denominator of a fraction must be multiplied by the same nonzero whole number in order to have equivalent fractions.You may be wondering why this is so.xample 4. Multiplying the numerator and the denominator of a fraction by the same nonzero whole number will change that fraction into an equivalent fraction, but it will not change its value. Equivalent fractions may look different, but they have the same value. Let's look at some more examples of equivalent fractions.
The smallest interval in use in the Western musical tradition is the semitone (also called half step). It is the interval between any note and its nearest neighbour on the keyboard. Two semitones together form one tone (or whole tone or whole step). Audio 1 From C to C# (or Db) is a semitone.From C# to D is also a semitone. Therefore from C to D is 2 semitones or 1 whole tone. (Down-Up-Top-Links) JT 1.2 - The Chromatic scale There are a total of twelve notes within an octave, represented by the 12 keys on the keyboard. All notes are spaced at semitone intervals.-note Diminished scale (tone-semitone-tone-semitone -) This scale starts with a tone between the tonic and 2nd note, then a semitone between the 2nd and 3rd notes, again a tone between the 3rd and 4th note, and so on. Audio 5 In Jazz this scale is used for improvisation over diminished chords (see Lesson 15).
