Hi guys, can someone pls explain how to divide fractions? pls and thank u
when dividing two fractions ex:
(1/3) / (1/6)
we take the reciprocal (we switch the bottom and top numbers) of the second fraction and then change the division into multiplication
(1/3) x (6/1)
multiply across to get
6/3
which is 2
hope this helps
keep the first set if fraction change the divison sign in to a multiplication. and flip the next set of numbers hope this helps

If each of the numbers in the following data set were multiplied by 18, what would be the new median of the data set? 14, 20, 18, 58, 71,36, 28
A. 360
B. 504
C. 648
D. 324
Answer:
Step-by-step explanation:
Arange the numbers in ascending order
14,18,20,28,36,58,71
You will see that the median of these data set is 28. So when you multiple it by 18, the answer will be 504.
Therefore, the answer is B. 504

Answer:
[tex]m=\sqrt{2}[/tex] inches
Step-by-step explanation:
From the diagram, it is given that the triangle is a right angle isosceles triangle (angles are 45°, 45° and 90°). This means that the two shorter sides of the triangle are equal in length and that the side [tex]m[/tex] can be found by using the Pythagorean theorem [tex]a^{2}+b^{2}=c^{2}[/tex].
[tex]m^{2}+m^{2}=2^{2}[/tex] (The two shorter sides of the triangle are equivalent)

[tex]m^{2}=2[/tex]
[tex]m=\sqrt{2}[/tex] inches

A rental car company charges drivers a flat fee to rent a car plus $0.25 for each mile they drive. If a driver pays
$100 and drives 160 miles, which equation can he use to find his total cost y in terms of the number of miles
driven x? SELECT ALL THAT APPLY
y = 25.2 + 100
y = .25x+ 140
y = .25x + 160
y - 100 = 25(x – 160)
0.25x + 100y = 160
25x – y = 14000
Answer: y-100= 0.25(x-160)
Step-by-step explanation:
Given: Charge per mile = $0.25
Total amount driver pays = $100
Number of miles he drove = 160 miles
Total cost = Flat fee + ( Number of miles he drove) (Charge per mile) ...(i)
i.e. 100= Flat fee + (160)(0.25)
⇒ Flat fee = 100 - (160)(0.25)
If y= total cost , x= number of miles, then
y= ( 100 - (160)(0.25))+ (x)(0.25) [Substitute value of flat fee in (i)]
⇒ y= 100 - (160)(0.25)+ (x)(0.25)
⇒ y-100= (x)(0.25)- (160)(0.25)
⇒ y-100= 0.25(x-160)
Hence, the required equation: y-100= 0.25(x-160)
Emily read 24 fiction books and 2 nonfiction books. What is the ratio of the number of fiction books she read to the total number of books that she
read?
Answer:
12:1 or 1:12
Step-by-step explanation:
For every 1 non fiction there is 12 fiction or for every 12 fiction there is 1 non fiction
The required ratio of the number of fiction books she read to the total number of books that she read is 12 / 13.
Given that,
Emily read 24 fiction books and 2 nonfiction books.
To determine the ratio of the number of fiction books she read to the total number of books that she read.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Number of fiction books = 24
number of nonfiction books = 2
Total number of books = 24 + 2 = 26
The ratio of a fiction book to the total number of books,
= 24 / 26
= 12 / 13
Thus, the required ratio of the number of fiction books she read to the total number of books that she read is 12 / 13.

What is a polynomial?An algebraic equation that has more than two terms, particularly the accumulation of numerous phrases that each include a different power of the same variable (s).
Given, P(x) is a polynomial. Here are a few values of P(x).
P(-6) = 3, P(-4) = -1, P(4) = 2, and P(6) = -5
The remainder theorem says that:
“When a polynomial p(x) is divided by (x−a), the remainder is p(a).
Since, p(6) is -5 and p(-4) is -1
Thus, the remainder when P(x) is divided by (x – 6) is -5
the remainder when P(x) is divided by (x + 4) is -1
Therefore, When Polynomial P(x) is divided by (x -6) and (x +4) the reminders would be -5 and -1 respectively.
