In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.
Answer: D
Im positive it is D and it might be 2.3333333333. But, i will stick with D.
Answer: (–1)(525) and (35)(–15) are equivalent to (- 7) (-15) (- 5)
Step-by-step explanation:
Given (- 7) (-15) (- 5)
To Find : Which two expressions that are equivalent (- 7) (-15) (- 5)
(–7)(–75) and (–1)(525)
(–1)(525) and (35)(–15)
(35)(–15) and (115)(–5)
(–1)(525) and (115)(–5)
Solution:
(- 7) (-15) (- 5)
= (105)(-5)
= - 525
(–7)(–75) and (–1)(525)
= 525 & - 525
not Equal
(–1)(525) and (35)(–15)
= -525 and - 525
Both Equal to (- 7) (-15) (- 5)
(35)(–15) and (115)(–5)
= -525 and - 575
not Equal
(–1)(525) and (115)(–5)
= -525 and - 575
not Equal
(–1)(525) and (35)(–15) are equivalent to (- 7) (-15) (- 5)
The pair of expressions equivalent to (Negative 7) (Negative 15) (Negative 5) are (Negative 7) (Negative 75) and (Negative 1) (525) because both pair of expressions result in -525.
The question asks which pair of expressions are equivalent to the expression (Negative 7) (Negative 15) (Negative 5). For this, we need to remember the rule in mathematics that the multiplication of two negative numbers gives a positive result and the multiplication of three negative numbers gives a negative result.
So, (Negative 7) (Negative 15) (Negative 5) equals to -7*15*5 = -525. Now, among the given options, the pair of expressions that are equivalent to -525 are (Negative 7) (Negative 75) and (Negative 1) (525), because -7*75 also equals -525, and -1*525 equals -525 as well.
Therefore, the pairs of expressions equivalent to (Negative 7) (Negative 15) (Negative 5) are (Negative 7) (Negative 75) and (Negative 1) (525).

The number which is written after rounding the number 9,740,399 to the nearest 100,000 is 9,700,000.
To write the large number at the nearest round, we use the nearest thousand of the number. The rounded to the nearest 100,000 of a number makes the calculation easy, and the result to understand batter.
To round a number to the nearest 100,000, follow the steps below-
The number given as,
This number has to be rounded to the nearest 100,000. The number at the 5 the place from left is 7.
The number immediate right is 4 which is less then 5. Thus, make all the number after 7 as zero,
Hence, the number which is written after rounding the number 9,740,399 to the nearest 100,000 is 9,700,000.

Answer:
is a whole number.
Step-by-step explanation:
Given : A fraction
We have to determine whether the given fraction equal to a whole number or a mixed number.
Whole numbers are those numbers that do not involves fractions.Example : 1, -10 , etc
Mixed numbers are numbers that are combination of an integers and a proper fraction. Example etc.
Consider the given fraction
45 can be written as product of 9 and 5
Thus, fraction becomes,
On simplifying, we get
Thus, 9 is an intger with no fraction.
Hence, is a whole number.
