How to convert a repeating decimal to a fraction

Mathematics
1 answer:
egoroff_w [7]3 years ago

Always place it out of 9. For example, 0.333= 3/9, or if simplified, 1/3.

0.5555? this will be 5/9.

for the other way around, make it a repeating decimal, such as 4/9, make that 0.444

If it is 33/99, or even 333/999, the rule should be the same.

Arlecino [84]

Answer:

1. 9/10  

2. 14/15

3. 1   1 /6 or 7/6

Step-by-step explanation:

1. Change the 5, the denominator to 10.  8/10

then add to 1/10  8/10 + 1/10= 9/10

2. Change both denimnators to 15. You will then get 9/15 and 5/15.

Add them together and get 14/15

3. Change both denominators to 6 and you will get 3/6 and 4/6.

Add them together to get 7/6.

If you want to make it into a mixed fraction it would be 1 1/6 (as in one and one-sixth)

Please help I’ll mark you as branlst
wariber [46]

Answer:

6

Step-by-step explanation:

Since the degree of the angle is 45, we know that the triangle is isosceles. That means that the sides of the triangle, not including the hypotenuse, has a length of 3√2.

Using the Pythagorean theorem, which is a^2 + b^2 = c^2, we have (3√2)^2 + (3√2)^2 = c^2.

Note: c is the hypotenuse of the triangle.

18 + 18 = c^2

= 36 = c^2

Therefore, c = 6.

What are the domain and range of f(x)=log(x-1)+2?
marta [7]

Answer: Domain = (-1, \infty)

Range = (-\infty, \infty)

Step-by-step explanation:

Here, the given function,

f(x) = log(x-1) + 2

Since log( negative number ) = not defined

Also,

log(0) = -\infty

Hence, f(x) is defined if x - 1 > 0

⇒ x > 1

Thus, f(x) is defined for all the values that are greater than 1,

⇒ Domain of f(x) = All real number greater than 1,

= (1, \infty)

Now, for the interval (1, \infty),

f(x) can be any real number.

Thus, the range of the given function = (-\infty, \infty)
