-3/5 divided by -3/4

Anuta_ua [19.1K]

4/5. To divide fractions, you multiply by the reciprocal (flip the second fraction). This gives us (-3/5) x (4/-3). Since there is a -3 on the top and the bottom, they cancel out. That leaves 4/5.

What is the probability that a randomly selected airline ticket is for an international flight?

Semenov [28]

Number of tickets for international flights = 36
Total number of tickets = 95
The probability that a randomly selected airline ticket is for an international flight = 36 / 95 = 0.3789

The probability that a randomly selected airline ticket is for an international flight as a percent rounded to the nearest tenth of a percent = 0.3789 x 100 = 37.9%

% of males surveyed = 0.236 + 0.218 = 0.454 = 45.4%
% of males surveyed who prefer chicken = 0.236 out of 0.454 = 0.236 / 0.454 = 0.5198 = 51.58% = 52.0%

What part of 3 12 is 1/2 ? I need this asap

Aliun [14]

I assume you are asking one of three things, so I will answer all of them.

if you are asking what is 1/2 of 312, then multiply 312 by 1/2. 312 is really just 312/1, so
$312 \times \frac{1}{2} = \frac{312}{1} \times \frac{1}{2}$
we multiply fractions by multiplying straight across
$\frac{312 \times 1}{1 \times 2} = \frac{312}{2} = 156$

if you were asking what part of 3 1/2 is 1/2 then we have to recognize what 3 1/2 is as an improper fraction. to do this, we convert 3 into halves. how many halves of pizza are there in 3 whole pizzas? 6. so we have 6 halves and one half, which is a total of 7 halves.
$\frac{6}{2} + \frac{1}{2} = \frac{7}{2}$
now, we do the same thing as the first problem
$\frac{7}{2} \times \frac{1}{2} = \frac{7 \times 1}{2 \times 2} = \frac{7}{4}$

if you were asking what is half of 3.12, then we convert 1/2 to a decimal and multiply
$\frac{1}{2} = .5 \\ 3.12 \times .5 = 1.56$

A club collected $1,085.00. If 75% of that came from membership dues, how much money came from sources other than membership?

bagirrra123 [75]

Answer:

100% - 75% = 25% so the answer is 25% of 1085 = 0.25 * 1085 = $271.25.

Answer:

1)x=-6,y=1 2)a=0,b=-8 3)j=8,k=1 4)m=3,n=-6

Step-by-step explanation:

1)x-4y=-10,2x+y=-11

x-4y=-10

x=4y-10

2\left(4y-10\right)+y=-11

8y-20+y=-11

9y-20=-11

9y=9

y=1

x=4-10

x=-6

x=-6,y=1

2)a-3b=24,a+2b=-16

a-3b=24

a=3b+24

3b+24+2b=-16

5b+24=-16

5b=-40

b=-8

a=3\left(-8\right)+24

a=-24+24

a=0

a=0,b=-8

3)k-j=-7

4j-5k=27,-j+k=-7

4j-5k=27

4j=5k+27

j=\frac{1}{4}\left(5k+27\right)

j=\frac{5}{4}k+\frac{27}{4}

-\left(\frac{5}{4}k+\frac{27}{4}\right)+k=-7

-\frac{1}{4}k-\frac{27}{4}=-7

-\frac{1}{4}k=-\frac{1}{4}

k=1

j=\frac{5+27}{4}

j=8

j=8,k=1

4)m+n=-3,m-4n=27

m+n=-3

m=-n-3

-n-3-4n=27

-5n=30

n=-6

m=-\left(-6\right)-3

m=6-3

m=3

m=3,n=-6
