All even numbers can be divided by 2. 6/100 = 3/50
Anything divided by one is the original number.
1 and 3/4 = 1.751 divided by 3 divided by 4 = 0.083333 repeating1 divided by 3/4 = 1.3333 repeating
1/6 is one fraction. You need at least two fractions to find something in common.
Assuming the domain and range are both the real numbers (or rationals): Yes, it is 1 to 1 Yes, it is onto and the inverse is x = (y-3)/4
the output is divided by 3.
No. The function y = x2, where the domain is the real numbers and the codomain is the non-negative reals is onto, but it is not one to one. With the exception of x = 0, it is 2-to-1. Fact, they are completely independent of one another. A function from set X to set Y is onto (or surjective) if everything in Y can be obtained by applying the function by an element of X A function from set X to set Y is one-one (or injective) if no two elements of X are taken to the same element of Y when applied by the function. Notes: 1. A function that is both onto and one-one (injective and surjective) is called bijective. 2. An injective function can be made bijective by changing the set Y to be the image of X under the function. Using this process, any function can be made to be surjective. 3. If the inverse of a surjective function is also a function, then it is bijective.
The output is multiplied by 3.
In simple words, a one-to-one function is a function such that for every input there is a unique output. An onto function is such that ALL the elements in the out are used, something which is not necessary for a one-to-one function. Draw a set A, which contains 3 elements, a, b, c and d. Draw another set B, containing elements e, f, g and h. Make an arrow from "a" to "d", "b" to "d", then "c" to "e" and "d" to "f". Draw the two sets A and B again. This time make an arrow from "a" to "d", "b" to "d", then "c" to "e" and "d" to "e". The fact that "f" in set B has not been used, DOES NOT makes this function an onto function.
The output is tripled.
It is: (1 and 1/9) divided by 1/3 = 3 and 1/3
3
It is: 1/3 divided by 1/9 = 3/1 => 3
2 and one fourth divided by 3 = 0.6666666666666666
the output is divided by 3.
The output is three times as large.
