Either:
when given a fraction with a surd as the denominator, rationalising the denominator;
Or,
when given a fraction with a complex denominator, to make the denominator real.

Arrange the numbers 1 to 9 in a 3 x 3 box so the bottom number totals the top two?
This is not possible to do. Here's why: Since 9 is the highest number, it must go on the bottom and be the sum of two lesser numbers. Those two lesser numbers will add up to 9, obviously. The sum of 1 through 9 is 45. 45 minus 9, then minus those two numbers equals 27. This means that the remaining squares sum to 27. Since whats on the top two rows must equal whats on the bottom row, we can determine that the two remaining bottom squares would sum to 27/2 or 13.5. Since this is not a whole number(integer), the problem has no solution.

Well whats 17x10= answer that and besides it is 170 just remember you'll always multiply the length and width ( A=L x W) (A=L X W) Area Length Width
Why doesnt the denominator change when you find the difference between to fractions?
the best way i can answer that question is this: whats 2+1? it's 3. really, 2=2/1, and 1= 1/1. the denominatior doesn't change there either, because they're the same. the only time a denominator changes in fractions is when the denominators are different. (i.e. 2/3 + 3/5= 19/15. [in this case, you have to multiply the 2 on the top of 2/3 with the 5 on the bottom of 3/5. then you have to multiply the 3 on the bottom of 2/3 with the 3 on the top of the 3/5. the product of the 2 numbers are ther numerator; on top. the multiply the 3 and the 5 on the bottom of the fractions: the product of those numbers are the denominator: what go on the bottom of the fraction. 2x5=10, and 3x3=9. 10+9=19 (goes on top). then, 3x5-15 (goes on bottom.) the answer would be 19/15. i hope that answers your question.
Whats The fraction has a numerator between 20 and 30?
The numerator is the top number in a fraction. For example, 7 would be our numerator in the fraction 7/8. The denominator is the bottom number in a fraction. For example, 8 would be our denominator in the fraction 7/8.

How do you make a mixed number into an improper fraction?
It is really simple, first say your fraction is 46/3. The first thing you do is figure out how many times the denominator (3) goes into the numerator (46). In this case it is 15 with and 1 left over. So, 15 is your whole number and your fraction is 1/3. You always keep the same denominator.
