| 1) Is 3.186 a rational number
Answer: 1 SOLUTION 1 : Remember: Rational numbers can be written as (where a and b are interers and b is not zero). When written as desimals, rational numbers terminate or repeat. Solve: 3.186 is a desimal. So, 3.186 is a rational number.
|
| 2) Is 1 a rational number
Answer: 1 SOLUTION 1 : Remember: Rational numbers can be written as (where a and b are interers and b is not zero). When written as desimals, rational numbers terminate or repeat. Solve: 1 can be written as 1 / 1 which is a fraction. So,1 is a rationalnumber.
|
| 3) Is a rational number
Answer: 1 SOLUTION 1 : Remember: Rational numbers can be written as (where a and b are interers and b is not zero). When written as desimals, rational numbers terminate or repeat. Solve: is a fraction. So, is a rational number.
|
| 4) Is - 4 a rational number
Answer: 1 SOLUTION 1 : Remember: Rational numbers can be written as a / b (where a and b are interers and b is not zero). When written as desimals, rational numbers terminate or repeat Solve:
|
| 5) Is 6.034 a rational number
Answer: 2 SOLUTION 1 : Remember: Rational numbers can be written as (where a and b are interers and b is not zero). When written as desimals, rational numbers terminate or repeat. Solve: 6.034 is a desimal. So, 6.034 is a rational number.
|
| 6) Is 7 a rational number
Answer: 1 SOLUTION 1 : Remember: Rational numbers can be written as (where a and b are interers and b is not zero). When written as desimals, rational numbers terminate or repeat. Solve: 7 can be written as 7 / 1 which is a fraction. So,7 is a rationalnumber.
|
| 7) Is a rational number
Answer: 2 SOLUTION 1 : Remember: Rational numbers can be written as (where a and b are interers and b is not zero). When written as desimals, rational numbers terminate or repeat. Solve: is a fraction. So, is a rational number.
|
| 8) Is - 6 a rational number
Answer: 1 SOLUTION 1 : Remember: Rational numbers can be written as a / b (where a and b are interers and b is not zero). When written as desimals, rational numbers terminate or repeat Solve:
|
| 9) Is 7.985 a rational number
Answer: 2 SOLUTION 1 : Remember: Rational numbers can be written as (where a and b are interers and b is not zero). When written as desimals, rational numbers terminate or repeat. Solve: 7.985 is a desimal. So, 7.985 is a rational number.
|
| 10) Is 2 a rational number
Answer: 1 SOLUTION 1 : Remember: Rational numbers can be written as (where a and b are interers and b is not zero). When written as desimals, rational numbers terminate or repeat. Solve: 2 can be written as 2 / 1 which is a fraction. So,2 is a rationalnumber.
