A rational number is any number that can be expressed as a ratio of two integers (hence the name "rational"). For example, 1.5 is rational since it can be written as 3/2, 6/4, 9/6 or another fraction or two integers. Pi (π) is irrational since it cannot be written as a fraction.
The decimal 2.5 is a rational number. The decimal 2.5 is equal to the fraction 25/10.
1.25 is a rational number. A rational number is any number that can be written as a fraction.
A Rational Number can be made by dividing an integer by an integer. (An integer itself has no fractional part.)...Example:NumberAs a FractionRational?1.757/4Yes10001000/1Yes.0011/1000Yes−0.1−1/10Yes
For example, 0.5 is a rational number. It is not a whole number, natural number, or integer, but it can be expressed as 1/2, which a fraction of two other integers: 1 is the numerator and 2 is the denominator. So, 0.5, or 1/2, is a rational number.
Yes, 1.25252525... is a rational number.
3/2Answer: 1.5 as a fraction is written as 3/2.
49 is a perfect square number which can be obtained by a square of 7 and it is also a composite number. Hence, the square root of 49 is a rational number....Square Root of 49.1.What Is the Square Root of 49?2.Is Square Root of 49 Rational or Irrational?3.How to Find the Square Root of 49?4.Important Notes5.Challenging Questions
Earlier, we said −2 is a rational number because we can express it as a ratio of two whole numbers. π is irrational because there are no two numbers you can divide and get exactly 3.141592654... .
1.2 = 12/10 , which is in the form p/q where p and q are integers and q 0. Numbers that can be written in the form p/q where p and q are integers and q not equal to zero.
So we can say it',s not an integer number or a natural number. The rational number 13/10 is real also, so we can say that 1.3 is a rational number.
Rational Numbers in decimal form Rational numbers can also be expressed in decimal form. Do you know 1.1 is a rational number? Yes, it is because 1.1 can be written as 1.1= 11/10. Now let's talk about non-terminating decimals such as 0.333..... Since 0.333... can be written as 1/3, therefore it is a rational number.
169=13 squared (132) , So square rooting the number: √169=13 . So, it is rational.
81 is a rational number.
Answer: 1.5 as a fraction is written as 3/2 Let's write 1.5 as a fraction.
It cannot be expressed as ratio of two integers and value of √3 = 1.7320508075688… which is non-termination non repeating. Hence, is an irrational number. Now, It can be represented in form p/q (p=4, q=5) where q≠0 and p,q have no common factor other than 1.
h) 6.920920920. . . Real, rational.
3/2Answer: 1.5 as a fraction is written as 3/2.
So, 18.788042... is irrational.
It is an Irrational Number! Again, 2.010010001… (is a non-terminating & non-recurring decimal) is an irrational number between 2 & 3. Considering the Given question of 2.010010001, 2 & 3 gives a rational number, as (2 + 3) / 2 gives 5 / 2 which is equal to 2.5 which is a rational number.
15 and 10 are both integers therefore 1.5 is a rational number.
Answer: a) 1.5 as a mixed number can be written as 1 1/2 b) 2.65 as a mixed number can be written as 2 13/20 c) 3.15 can be written as 3 3/20. Explanation: To express 1.5 as a fraction, we need to write the given decimal number in the x/y form, where x and y are the positive integers.
You can be living with an STI for years without knowing it. Even when STIs don't have obvious symptoms, they can still be damaging. Untreated, asymptomatic STIs can: increase the risk of infertility.
Since bacterial STIs cannot survive outside the environment of mucous membranes in the body, it is essentially impossible to contract one by sitting on public toilet seats. Viral causes of STIs cannot survive for long outside the human body either, so they generally die quickly on surfaces like toilet seats.
