The fraction is 35/56.
The way to find it is as follows:
1) n/d = 5/8
2) (n-5) / (d+4) = 1/2
3) n = (5/8)*d [rearrange (1)]
4) 2*(n-5) = (d+4) [rearrange (2)]
5) 2*n - 10 = d + 4 [rearrange (4)]
6) 2*n = d + 14 [rearrange (5)]
7) 2*((5/8)*d) = d + 14 [substitue (3) into (6)]
8) (10/8)*d = d+14 [rearrange (7)]
9) (10/8)*d - d = 14 [rearrange (8)]
10) (10/8)*d - (8/8)*d = 14 [rearrange (9)]
11) (2/8)*d = 14 [rearrange (10)]
12) d = 14 / (2/8) = 14 * 8/2 [rearrange (11)]
13) d = 112/2 = 56 [simplify (12)]
14) n = (5/8)*56 [substitute (13) into (3)]
15) n = 280/8 = 35 [simplify (14)]
16) THE ANSWER IS n/d = 35/56 [substitute (13) and (15) into the definition of the fraction]
Multiply it by a fraction that has a certain number of inches in the numerator and the same length as the numerator but in the units of the given height in the denominator. The original units cancel out, and you're left with inches. If the numerator and denominator of a fraction are equal, the fraction is equal to 1, and multiplying something by 1 does not change its value.
if you multiply a number by a certain factor and then divide it by the same factor you do not change anything. It is like multiplying by 1. If you multiply only the numerator you have changed the answer and it is not equivalent.
A fraction with a denominator of 1 must also have a numerator of 1, assuming you are describing a single object with a ratio. The numerator can be greater than 1, but than means you are creating a ratio exceeding the denominator. Example: 2/1 means you have double the object being represented by the fraction. Any fraction with a denominator greater than 1 can mean multiple things: You have multiple pieces of an object You have multiple objects and the numerator represents the number of the objects meeting a certain condition ..And so on. The idea is that it's subjective to whatever the fraction is representing.
Probably is a decimal....not suree...ohhh welll.. lol
The majority of fractions will not be able to become whole numbers. Certain improper fractions, where the numerator is a multiple of the denominator, can become whole numbers. No proper fractions can.

To convert a vulgar fraction into a mixed number, you need to subtract the denominator from the numerator a certain number of times such that the numerator is less than the denominator. In the case of 45/12, we can subtract 12 from 45 three times to leave us with 9/12. Both these numbers can be divided by 3, so we can simplify it to 3/4. We subtracted 12 three times so need to write that as the units. Thus, as a mixed number, 45/12 would be 3 and 3/4.
per cent (or %) Literally from the Latin "in every hundred", so it is a fraction with denominator of 100 replaced by this phrase, or by the symbol %, So, 25 percent = 25% = 25/100 which is 1/4.
An improper fraction would be defined as a fraction for which the numerator (the number on top) is larger than the denominator (the number on the bottom). So, the numerator will have a certain number of multiples of the denominator; for example, if the denominator is 3 then the fraction is a certain number of thirds, and for every 3 thirds, you can convert that to the number one. So 3/3 is 1, 6/3 is two, 9/3 is 3. 12/3 is 4 and so forth. If the denominator is 5, then you have fifths, and each five of them is a number one, so 5/5 is 1, 10/5 is two, 15/5 is three, etc. So after you subtract the multiples of the denominator, you may have some number left which is still a fraction. For example if you have 10/3, you can subtract the 9/3 which is equal to 3, and you still have 1/3 left. Therefore, 10/3 equals 3 and a third.
This becomes easier with experience and having the ability to recognise that certain numbers are factors of both the numerator and denominator. Until this experience is gained simply try dividing the numerator and denominator by prime numbers of increasing value. (2, 3, 5, 7, 11, 13, 17 etc) Obviously if this division is successful then the fraction can be simplified but this does not necessarily mean further simplification is not possible. Simplification ceases when either the numerator or the denominator becomes a prime number or has the value 1. This last condition usually applies to just the numerator. All non-prime numbers can be factored into prime numbers so it is only necessary, at this stage, to divide using prime numbers.
that means that you have perfect vision__________________________________________________________The numerator refers to within what distance of certain objects you have to be to distinguish them. The denominator refers to within what distance of certain objects a "normal" person has to be to distinguish them. Therefore, 25/25 vision is much like 20/20 vision in that it indicates normal/perfect vision. If the numerator is greater than the denominator (20/15), one's vision is better than normal. If the denominator is greater than the denominator (20/40), one's vision is worse than normal.
There is an infinite number of fractions for those numbers. However in simplest form it is 1/4 and 1/2 but you can multiply the numerator and denominator by any number to get an equivalent fraction. If you just need to list a certain number of these fractions you could multiply the top and the bottom times two to get an equivalent fraction and do it however many times you need fractions.
