-0.35 = - (35/100) = -7/20
(8/15) / (7/20) = (8/15) * (20/7) = (8*20) / (15*7)
= 160/105 = 32/21

Hi, I'm happy to help!

To solve this problem, we can turn -0.35 into an equivalent fraction.

\frac{8}{15}÷\frac{-0.35}{1}

For division, I like to use the strategy called KFC. This stand for Keep, flip, and change. You keep the first fraction, flip the second, and change the operation.

\frac{8}{15}×\frac{1}{-0.35}

Now we multiply the top by the top and the bottom by the bottom.

\frac{8}{-5.25}

We know that the negative applies to the entire fraction, so we write it like this:

-\frac{8}{5.25}

I hope this was helpful, keep learning! :D

Kayla and Bianca each bought one raffle ticket at the school fair. If 50 tickets were sold, what is the probability Kayla bought
Leona [35]

The total tickets sold at the fair = 50 tickets.

Kayla and Bianca each bought one ticket, it could be any numbered. We can start with anyone and find their probability.

If Kayla got ticket numbered #7, its probability would be 1 out of 50.  

Then there would be 49 tickets remaining for Bianca at the fair.

If Bianca got ticket numbered #10, it probability would be 1 out of 49.

Total probability of (Kayla getting #7 AND Bianca getting #10) would be 1/(50x49) = 1/(2,450) = 0.0004081 = 0.0408%.

Hence, final answer is \frac{1}{2,450} \;or\; 0.0004081 \;or\; 0.0408\%.

A florist sells a bouquet of roses
NikAS [45]

Answer:

Bouquets of roses = 20

Bouquets of carnations = 08

Step-by-step explanation:

Let,

x be the bouquets of roses sold

y be the bouquets of carnations sold

According to given statement;

x + y = 28       Eqn 1

16x + 10y = 400     Eqn 2

Multiplying Eqn 1 by 16

16(x+y=28)

16x + 16y = 448    Eqn 3

Subtracting Eqn 2 from Eqn 3

(16x+16y)-(16x+10y) = 448 - 400

16x + 16y - 16x - 10y = 48

6y = 48

Dividing both sides by 6

\frac{6y}{6}=\frac{48}{6}\\y=8

Putting y=8 in Eqn 1

x + 8 = 28

x = 28 - 8

x= 20

Hence,

Bouquets of roses = 20

Bouquets of carnations = 08
