\dfrac{9}{10}=\dfrac{1}{2}+\dfrac{1}{3}+\dfrac{1}{15}

\dfrac{1}{2}=\dfrac{15}{30}\\\\\dfrac{1}{3}=\dfrac{10}{30}\\\\\dfrac{1}{15}=\dfrac{2}{30}\\\\\dfrac{1}{2}+\dfrac{1}{3}+\dfrac{1}{15}=\dfrac{15}{30}+\dfrac{10}{30}+\dfrac{2}{30}=\dfrac{15+10+2}{30}=\dfrac{27}{30}=\dfrac{9}{10}

On Dan's eReader, 2/3 of the books are fiction. Of the fiction books,4/5 are mysteries. What fraction of the books on Dan's eRea
Nitella [24]

Answer:

Step-by-step explanation:

Let's take a real situation. Suppose he has 1500 books in total

2/3 of them are fiction. Of means multiply.

them = 1500

2/3 * 1500 = 3000/3 = 1000

Now of the one thousand fiction books 4/5 of them are mysteries.

4/5 * 1000 = 4000/5 = 800.

Now let's see what happens when we just do this by answering the question directly.

2/3 * 4/5 = 8/15 This has the meaning that 8 out of every 15 books = mysteries.

Try this on the 1500 books.

8/15 * 1500 = 9000/15 = 800. So the answers are the same and the answer the computer expects should be 8/15 or 0.533333333

Just to check, does 0.5333333 * 1500 = 800? Try it.

Which expression is a perfect cube
mamaluj [8]

Answer: some perfect cubes are

8 (2^3)

27 (3^3)

64 (4^3)

there are many perfect cubes

maybe there is more to this question?

Step-by-step explanation:

A perfect cube of a number is a number that is equal to the number, multiplied by itself, three times. If x is a perfect cube of y, then x = y3. Therefore, if we take the cube root of a perfect cube, we get a natural number and not a fraction. Hence, 3√x = y. For example, 8 is a perfect cube because 3√8 = 2.
