How do you write 1.12 as a fraction?
112 is an integer and not a fraction. However, it can be expressed in rational form as 112/1. You can then calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any non-zero integer.
What is the value of A if A is an integer?
"Integer" means "whole number". From everything you've told us, all we know about 'A' is that it's a whole number.
Can you add two rational number to get irrational number?
Yes, we can get a rational number on the addition of two irrational numbers.e.g. Let us consider two irrational numbers: 3 + √2 and 4 - √2.Addition yields:(3 + √2)+ (4 - √2) = 3 + 4 = 7(a rational number).Another example is:Addition of √2 and -√2.√2+ (-√2) = 0(a rational number).Explanation of example 1:Irrational numbers in the form of of p + q are are the irrational numbers which are obtained on addition of two terms: one is rational(p) and another is irrational(q).And on taking the conjugate of p + q we get p - q, which is an another irrational number. And the addition of these two yields a rational number.
What is a product of a number multiplied by a whole number?
We know that one of these numbers is a whole number, but we don't know what kind of number the other is, so this statement doesn't tell us anything. We can make different assumptions about the first number, though, and make conclusions that way.Let X be the first number of unknown type, and Y be the whole number, "whole number" meaning the subset {0, 1, 2, 3, …} of the integers. Then:if Y is an integer (any element of the set {…, -2, -1, 0, 1, 2, …}, then the product of X and Y is an integer.if X is a negative integer, the product of X and Y is a negative integer or 0 (which would happen when Y is 0).if X is 0, the product of X and Y is 0.if X is a non-integer rational number, and this rational number can be expressed with a denominator equal to Y, then the product of X and Y is the numerator of X. For example, if X is 20/4 and Y is 4, the product of the two is 20.You can make other rules like this for other situations.
Ask us anythingA rational number is a number that can be written as a .?
fraction, a ratio of two integers p/q where q is not equal to zero.
Why is the product of any two rational numbers a rational number?
Rational numbers are represented in the form of p/q , where p is an integer and q is not equal to 0.Every natural number, whole number and integer can be represented as rational number.For example take the case of integer -3, it can be represented in the form of p/q as -3/1 and q is not equal to zero, which means that rational numbers consist of counting numbers, whole numbers and integers.Now, what will be the result of product of any two rational numbers?Let us take the case of two rational numbers which are x/y & w/z, their product is equal toxw/yz, which is a rational number because multiplication of x and w results in an integer and also multiplication of y and z results in an integer which satisfies the property of rational numbers, which is in the form of p/q.So, product of any two rational numbers is a rational number.
Math help can anyone show you how to do this please Prove or disprove that if a and b are rational number then ab is rational?
To prove a number ab is rational, you have to find two integers t and n such that t/n = ab.Since we know that a, and b are rational, they can be expressed as follows:a = p1/q1b = p2/q2then ab = p1p2/q1q2Since p1, p2, q1, and q2 are all integers, p1p2 is an integer, and q1q2 is an integer. This gives us the t, and n we are looking for. t = p1p2 and n = q1q2, and ab = t/n, so ab is rational.
How do you write 1.12 as a fraction?

Is there a rational number between any two distinct rational numbers?
Yes. Not only that, but there are an infinite number of rationals between any two distinct rationals - however close. We can prove it like this: Take any three rational numbers, call them A, B and C, where B is larger than A, and C is any rational number greater than 1: D = A + (B - A) / C That gives us another rational number, D, no matter what the values of the original numbers are.
What is the value of A if A is an integer?
"Integer" means "whole number". From everything you've told us, all we know about 'A' is that it's a whole number.
Is this number 2.247.000 rational or irrational?
We don't understand a number with two decimal points in it. If you mean the number that we would write with commas in the US: 2,247,000 then that number is rational.
What us 26 as a fraction in simplistt form?
26 is an integer and not a fraction. However, it can be expressed in rational form as 26/1 which cannot be simplified.
True or false 0 us a rational number?
True.
If you add a rational and irrational number what is the sum?
an irrational number PROOF : Let x be any rational number and y be any irrational number. let us assume that their sum is rational which is ( z ) x + y = z if x is a rational number then ( -x ) will also be a rational number. Therefore, x + y + (-x) = a rational number this implies that y is also rational BUT HERE IS THE CONTRADICTION as we assumed y an irrational number. Hence, our assumption is wrong. This states that x + y is not rational. HENCE PROVEDit will always be irrational.
How many rational numbers are between 2 and 3?
There are infinite rational numbers between 2 and 3.Explanation:Let us write a few decimal numbers between 2 and 3: 2.01, 2.001, 2.0001,.., 2.4, 2.90 etc. Just change digits after the decimal point and this way we can write infinite decimal numbers between 2 and 3. And each decimal number can be expressed in the form of p/q(rational number)2.01 = 201/1002.001 = 2001/1000... 2.4 = 24/10 and so on.So there are infinitely many rational numbers b/w 2 and 3.
Can you add two rational number to get irrational number?

And the addition of these two yields a rational number.
Is a decimal ending in the number 5 with 2 in the ones digit considered an even or odd number?
All numbers that are divided evenly by 2 are even numbers, otherwise they are odd. So that ... 2.5 tells us that its product with 2 is an odd number (2 in the ones place doesn't mean anything). Since ... 2.5 is a rational number it can be written as a fraction (integer/integer). It can be ...25/2, ...25/10, ...250/4, ... So we cannot determine ...2.5 as even or odd.
