put the fraction in least to greatest denomenator then put them in order please help me 1/2 3/4 1/5 7/10 please help me
DiKsa [7]

Working with fractions, you'll need to find the least common denominator (LCD). In this case, the LCD is 20.


Rewriting the four given numbers to the LCD, you would get:

10/20, 15/20, 4/20, and 14/20.


Now, you just organize it from least to greatest as:

4/20 < 10/20 < 14/20 < 15/20.


In other words, it is:

1/5 < 1/2 < 7/10 < 3/4.

Twelve books cost $59.88 and 21 books cost $104.79. Is there is a constant of proportionality between these purchases? Select th
Anit [1.1K]

Answer:

There is a constant of proportionality between the two purchases and each book costs $4.99 (option B).

Step-by-step explanation:

A correspondence relation between two variables is of direct proportionality when the quotient between the corresponding quantities is always the same. This quotient is called the constant of proportionality.

In other words, when dividing any quantity of one of the magnitudes by the one that corresponds to it in the other, the value it gives is always the same. This value is known as the constant of proportionality.

In this case, the constant of proportionality k will relate the number of books bought N and their cost C in the following way:

C=k*N

So  k is the price per book.

For the 12 books:

k=\frac{59.88}{12}

k=4.99

And for the 21 books:

k=\frac{104.79}{21}

k=4.99

The constant k  for the two purchases is the same, thus <u><em>there is a constant of proportionality between the two purchases and each book costs $4.99 (option B). </em></u>

The panthers team won exactly 2 of its first 9 games. By winning all its remaining N games, the Panthers ended with victories in
Soloha48 [4]

Answer:

5

Step-by-step explanation:

2 out of 9 games won

After the N games, the games won would be HALF. Thus, we can write a ratio and solve for the variable N:

\frac{2+N}{9+N}=\frac{1}{2}

Now we cross multiply and solve for N [the number of remaining games that all are won]:

\frac{2+N}{9+N}=\frac{1}{2}\\2(2+N)=1(9+N)\\4+2N=9+N\\2N-N=9-4\\N=5

N represents 5
