The relative pronoun "that" is used with essential clauses, also known as restrictive clauses, which are necessary for the sentence's meaning to be complete. These clauses provide essential information that cannot be omitted without changing the sense of the sentence. For example, "The book that I bought yesterday is excellent." Here, the clause "that I bought yesterday" is necessary to identify which book is being referred to.
On the other hand, the relative pronoun "which" is used with nonessential clauses, also known as non-restrictive clauses, which provide additional information but do not change the sentence's core meaning if omitted. These clauses are often set off with commas. For example, "The book, which was recommended by my friend, is excellent." In this case, "which was recommended by my friend" provides extra information about the book, but it can be removed without affecting the main point of the sentence.
The key difference between essential and nonessential clauses is that essential clauses are crucial to the sentence's meaning and cannot be omitted, while nonessential clauses provide additional detail but are not necessary for the sentence's core meaning.
The relative pronoun that is used with an essential clause, and the relative pronoun which is used with a nonessential clause. In 3–5 sentences, explain when to use each pronoun and the difference between the two types of relative clauses.

Multiply 49 by −3. Write the answer as a mixed number in simplest form.(1 point)
49 multiplied by -3 equals -147. In mixed number form, this can be written as -147.
Multiply 4/9 by −3. Write the answer as a mixed number in simplest form.(1 point)
To multiply 4/9 by -3, we can multiply the numerators and denominators separately:
(4 * -3) / (9 * 1).
This simplifies to -12/9.
To convert it to a mixed number in simplest form, we divide the numerator by the denominator:
-12 ÷ 9 = -1 remainder -3.
Therefore, the answer as a mixed number in simplest form is -1 and 3/9, which can be further simplified to -1 and 1/3.
(4 * -3) / (9 * 1).
This simplifies to -12/9.
To convert it to a mixed number in simplest form, we divide the numerator by the denominator:
-12 ÷ 9 = -1 remainder -3.
Therefore, the answer as a mixed number in simplest form is -1 and 3/9, which can be further simplified to -1 and 1/3.
Multiply 2/3 by 1 1/4. Write the answer in simplest form.(1 point)
To multiply 2/3 by 1 1/4, we first need to convert the mixed number 1 1/4 into an improper fraction.
1 1/4 can be written as (4 * 1 + 1) / 4 = 5/4.
Now, we can multiply the fractions:
(2/3) * (5/4) = (2 * 5) / (3 * 4) = 10/12.
To simplify this fraction, we can reduce it by dividing both the numerator and denominator by their greatest common divisor, which in this case is 2:
(10/2) / (12/2) = 5/6.
Therefore, the answer, in simplest form, is 5/6.
1 1/4 can be written as (4 * 1 + 1) / 4 = 5/4.
Now, we can multiply the fractions:
(2/3) * (5/4) = (2 * 5) / (3 * 4) = 10/12.
To simplify this fraction, we can reduce it by dividing both the numerator and denominator by their greatest common divisor, which in this case is 2:
(10/2) / (12/2) = 5/6.
Therefore, the answer, in simplest form, is 5/6.

To multiply -2/5 by 3/10, we multiply the numerators and denominators:
(-2 * 3) / (5 * 10) = -6/50.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2:
(-6/2) / (50/2) = -3/25.
Therefore, the answer, in simplest form, is -3/25.
(-2 * 3) / (5 * 10) = -6/50.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2:
(-6/2) / (50/2) = -3/25.
Therefore, the answer, in simplest form, is -3/25.

To multiply 4 by -5/8, we multiply the whole number (4) by the numerator (-5) and keep the denominator (8) the same:
4 * (-5) / 8 = -20 / 8.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 4:
(-20/4) / (8/4) = -5/2.
Therefore the answer, in simplest form, is -2 1/2.
4 * (-5) / 8 = -20 / 8.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 4:
(-20/4) / (8/4) = -5/2.
Therefore the answer, in simplest form, is -2 1/2.

To multiply -2 1/2 by -1 3/5, we first need to convert the mixed numbers into improper fractions:
-2 1/2 = (-2 * 2 + 1) / 2 = -5/2.
-1 3/5 = (-1 * 5 + 3) / 5 = -8/5.
Now, we can multiply the fractions:
(-5/2) * (-8/5) = (5 * 8) / (2 * 5) = 40/10 = 4.
Therefore, the answer as a decimal is 4.
-2 1/2 = (-2 * 2 + 1) / 2 = -5/2.
-1 3/5 = (-1 * 5 + 3) / 5 = -8/5.
Now, we can multiply the fractions:
(-5/2) * (-8/5) = (5 * 8) / (2 * 5) = 40/10 = 4.
Therefore, the answer as a decimal is 4.
