Which number is irrational?
√5
0.3
0.777...
0.454545...
1 year ago
The number that is irrational is √5.
√5 is the square root of 5, and it cannot be expressed as a fraction or terminating decimal. Therefore, √5 is an irrational number.
0.3, 0.777..., and 0.454545... are all rational numbers as they can be expressed as fractions or terminating decimals.

The number that is rational is 0.83587643.
A rational number is one that can be expressed as a fraction of two integers. 0.83587643 can be expressed as a fraction since it terminates, making it a rational number.
0.333... is a repeating decimal, but it can be expressed as a fraction of 1/3. Therefore, it is also rational.
π (pi) and √7 (square root of 7) are both irrational numbers as they cannot be expressed as fractions of two integers.

Which number produces a rational number when multiplied by 0.5?
√3
-1.73205089
1/3
0.54732814
1 year ago
The number that produces a rational number when multiplied by 0.5 is 1/3.
Multiplying 1/3 by 0.5 gives us 1/6, which is a rational number.
√3 and -1.73205089 are both irrational numbers, and multiplying them by 0.5 would still result in irrational numbers.
0.54732814 is a rational number, but when multiplied by 0.5, it results in a decimal that is not exactly representable as a fraction. Therefore, it does not produce a rational number when multiplied by 0.5.

Which number produces a rational number when added to 1/5?
- 2/3
√11
π
-1.41421356
1 year ago
The number that produces a rational number when added to 1/5 is -2/3.
When you add -2/3 to 1/5, you get (-2/3) + (1/5) = ( -10/15 ) + ( 3/15 ) = -7/15, which is a rational number.
√11, π, and -1.41421356 are all irrational numbers, and adding them to 1/5 would result in irrational numbers.
