What is -3/8 divided by 7/12 A. -32/7 B.-14/9 C. -9/14 D. -7/32

1 answer:

5 0

To divide fractions, you flip the second one and multiply them so it would be:
(-3/8) / (7/12)
-3/8 * 12/7
-36/56
This can be simplified to :
-9/14
Because you divide both the numerator and denominator by 4.

Hope this helps :)

Hi ;-)

$-\frac{1}{3}-(-\frac{1}{2})=-\frac{1}{3}+\frac{1}{2}=-\frac{2}{6}+\frac{3}{6}=\frac{3}{6}-\frac{2}{6}=\frac{1}{6}\\\\3\frac{1}{3}-5=-(5-3\frac{1}{3})=-(4\frac{3}{3}-3\frac{1}{3})=-1\frac{2}{3}\\\\-1\frac{4}{5}-(-2\frac{7}{8})=-1\frac{4}{5}+2\frac{7}{8}=-1\frac{32}{40}+2\frac{35}{40}=2\frac{35}{40}-1\frac{32}{40}=1\frac{3}{40}\\\\-3\frac{3}{8}-\frac{7}{8}=-(3\frac{3}{8}+\frac{7}{8})=-3\frac{10}{8}=-3\frac{5}{4}=-4\frac{1}{4}\\\\4\frac{3}{4}-(-1\frac{1}{12})=4\frac{9}{12}+1\frac{1}{12}=5\frac{10}{12}$

Amy has 12 pairs of white socks, 2 pairs of gray socks, and 6 pairs of black socks in her drawer. if she takes two pairs without

KIM [24]

HI!
First of all, there are total 12 + 2 + 6 = 20 pairs of socks.
Probability of getting a pair of white socks the first time is 12/20.
Probability of getting a pair of gray socks without replacement, if first one was white, is 2/19
Therefore the probability t<span>hat she will take a white pair and gray pair</span> without replacement is 6/95 (I multiplied the two probabilities)
Let me know if there are any other questions!

The mass would be 6x10^6

The volume of a cylinder is 675π cm3. The radius of the base of the cylinder is 5 cm. What is the height of the cylinder?

frosja888 [35]

Answer: 27 cm

Step-by-step explanation:

We know that the volume of a cylinder is $V=\pi r^2h$ . Since we were given the volume and radius, we can plug them in and solve for height.

$675\pi =\pi (5^2)h$ [divide both sides by π]

$675 = (5^2)h$ [exponent]

$675=25h$ [divide both sides by 25]

$h=27$

Now, we know that the height is 27 cm.
