If there are three thirds in one, there must be six thirds in two.

You first work out the fraction of the number, Then you figure out to the nearest whole. Like if it was 1\5 of 150 if its 1\5th of 150 - 30 then you round it two the nearest number.

Given any whole number, x, you can write it as a rational traction in the form x/1. You can then multiply both the numerator and denominator by any non-zero integer to make an equivalent fraction.

In a fraction you are looking at parts of a whole, thus if you think of this as a pie and the lower number as the number of pieces the pie has been cut into. the top number of pieces you intend to remove or work with. thus your query of what does 2/3 equal... If you cut each piece of pie into another equal piece then the answer 4/6 is correct. the denominator is the lower number or the total number of pieces that the pie is cut up into. the numerator is the number of pieces you plan to work with or eat...

When working with mixed numbers it is almost always easier to convert them to improper fractions first, do the whatever (with the improper fraction just like an ordinary fraction) and convert any final improper fraction into a mixed number. To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator to form the new numerator and keep the denominator the same. For example: 2 3/7 → (2x7+3)/7 = 17/7 To convert an improper fraction to a mixed number divide the numerator by the denominator to get a whole number quotient and a remainder. The whole number quotient is the whole number and the remainder is put as the numerator over the original denominator as the fraction. For example: 17/7 → 17 ÷ 7 = 2 r 3 → 17/7 = 2 3/7

To find this fraction, you will need to divide the whole fraction by a number. This number must divide 75 into a whole number and 100 into a whole number. So think, what number can divide both 75 and 100? One number is 5. Another is 25. Both work, but let's start with 5:75 divided by 5 = 15100 divided by 5 = 20 So now we have the fraction 15/20. But this is still now in simplest form. We divide the whole fraction by 5 and get 3/4. Now, try putting 75/100 in simplest form using 25 as the divisor for practice.

E.g. 8/4 turned to whole number 8 divided by 4 = 2 2 is the answer It won't work for most fractions tho because most will have remainders

No. An irrational number isn't a whole number, nor can it be represented exactly as a fraction of two whole numbers. 50 is a whole number, so it's rational. 50/3, while having a repeating decimal, is still rational because it's an exact fraction. The square root of two is irrational because there is no fraction that can exactly represent it. The same goes for pi (although 22/7 is close enough for government work -- jk).

To simplify a fraction, you find a number that can be divided by the fraction you are simplifying. sometimes this does not always work and the fraction can not be simplified.

if your numbers arent whole numbers then multiply them out until they are whole numbers that are easier to work with.

The best way to multiply a whole number by a fraction is to tackle the problem in two parts. First you multiply the number by the numerator (top) of the fraction. Second you divide the number by the denominator (bottom) of the fraction. For example, if I wanted to work out 25 x 4/10 I would do 25x4, which = 100 Then I would do 100/10, which = 10, so the answer is 10. This is only the mental method though. When writing down on paper you would do this all in one step, as 25 x 4/10 = 10.
