Unlike fractions: ones with different denominators.
Like fractions: ones with the same denominator.

Examples:
1/3 and 1/4 are unlike fractions, because their denominators are different.
1/3 and 1/6 are also unlike fractions, because their denominators are different.
2/13 and 17/13 are like fractions, because their denominators are the same.

<em>Comment on like/unlike fractions</em>
In general, addition and subtraction must be carried out on <em>like</em> fractions. That is, for unlike fractions to be added or subtracted, they must first be converted to like fractions. This is done by expressing both fractions using a common denominator. The common denominator is often chosen as the Least Common Multiple (LCM) of the two denominators, but it can be simply the product of the denominators:
a/b + c/d = (ad)/(bd) +(bc)/(bd) = (ad +bc)/(bd)
The reason for using the LCM of the denominators is that it <em>may</em> save work in reducing the final sum to lowest terms.
The trick with answering your 10s, 100s, 1000s, etc, is just adding zeroes onto the ends of the first number. So, since this is 14 times 1000, you would add 3 zeroes onto 14. So your answer is 14,000. Hope this helped!

Answer:
1.17
Step-by-step explanation:
(MUCH BETTER!)
From the definition of the sin of an angle, you know:
sin(45°) = AC/AB = 4/AB ⇒ AB = 4/sin(45°) ≈ 5.6569
sin(63°) = AC/AD = 4/AD ⇒ AD = 4/sin(63°) ≈ 4.4893
Then the difference AB-AD is:
AB -AD = 5.6569 -4.4893 = 1.1676
AB -AD ≈ 1.17 units
Sorry this took me so long to answer!
