A rational number can be written as the ratio of one blank to another and can be represented by a repeating or blank decimal

Answers

Answer 1

Answer:

we know that

A rational number is the quotient of two integers with a denominator that is not zero , and can be represented by a repeating or terminating decimal.

Repeating Decimal is a decimal number that has digits that go on forever

Terminating decimal is a decimal number that has digits that do not go on forever.

examples

$(1)/(3) = 0.333...$ (the $3$ repeats forever)----> Is a Repeating Decimal

$0.25$ (it has two decimal digits)----> Is a Terminating Decimal

therefore

the answer is

A rational number can be written as the ratio of one $integer$ to another and can be represented by a repeating or $terminating$ decimal

Answer 2

Answer: A rational number can be written in the form:

$(p)/(q); \ called \ the \ ratio \n \n where \ p \ and \ q \ are \ whole \ numbers$

The number $q$ isn't equal to zero because the division by zero is not defined. So we can represent rational numbers by a repeating or terminating decimal, for instance in the following four exercises we have:

$(2)/(3)=0.6666...=0.\stackrel{\frown}{6} \n \n (5)/(8)=0.625000...=0.625\stackrel{\frown}{0} \n \n (3)/(1)=3.000...=3.\stackrel{\frown}{0} \n \n (3446)/(2475)=1.392323...=1.39\stackrel{\frown}{23}$

How can you solve problems involving equations that contain addition, subtraction, multiplication, or division?

Answers

Well it all depends on the problem but you have to approach every problem with the order of operations PEMDAS. In order you do parentheses, exponents, multiplication, division, addition, then subtraction. If you post an example of the problem you're trying to work out we can be more specific.

A count went from 605 to 203. What was the approximate percent decrease? Round the numbers to find an estimate of the percent decrease. The percent decrease was approximately 25%. The percent decrease was approximately 33%. The percent decrease was approximately 50%. The percent decrease was approximately 66%.

Answers

66% It is 66% because 203 is less than half of 605. So, you would add that together. 203+203=406 Thats not even close to 605 so now you add almost half so that would be about 66%

Answer:

Decrease was 66%

12 2/3 ^ 2 1/3what is 12 2/3 divided by 2 1/3

Answers

Answer:

(12 2/3)/( 2 1/3)= 38/7 or 5 3/7 or 5.43 decimal

Step-by-step explanation:

Simplify the following:

(12 + 2/3)/(2 + 1/3)

Put 2 + 1/3 over the common denominator 3. 2 + 1/3 = (3×2)/3 + 1/3:

(12 + 2/3)/((3×2)/3 + 1/3)

3×2 = 6:

(12 + 2/3)/(6/3 + 1/3)

6/3 + 1/3 = (6 + 1)/3:

(12 + 2/3)/((6 + 1)/3)

6 + 1 = 7:

(12 + 2/3)/(7/3)

Put 12 + 2/3 over the common denominator 3. 12 + 2/3 = (3×12)/3 + 2/3:

((3×12)/3 + 2/3)/(7/3)

3×12 = 36:

(36/3 + 2/3)/(7/3)

36/3 + 2/3 = (36 + 2)/3:

((36 + 2)/3)/(7/3)

36 + 2 = 38:

(38/3)/(7/3)

Multiply the numerator by the reciprocal of the denominator, (38/3)/(7/3) = 38/3×3/7:

(38×3)/(3×7)

(38×3)/(3×7) = 3/3×38/7 = 38/7:

Answer: 38/7
