I need help with improper fractions may you please help me thanks


An improper fraction is simply a fraction with the numerator being larger than the denominator.

To make it an improper fraction from the mixed number given, just multiply the whole number (2) by the denominator (3), then add the numerator (2). The result is the new numerator and the denominator remains the same.

In this case (2 2/3), it would be 2 * 3 + 2 for the numerator....or 8. So 8/3 would be the improper fraction.

How to solve franctions


Multiplying Fractions:
  1. Make sure you're working with two fractions.
  2. Multiply numerator x numerator, then multiply denominator x denominator.
Dividing Fractions:
  1. Make sure you're working with two fractions
  2. Flip the second fraction upside down.
  3. Change the division sign into a multiplication sign.
  4. Multiply top x top and bottom x bottom.
Converting Mixed Numbers into Improper Fractions:
  1. Convert mixed numbers into improper fractions.
  2. Take the whole (non-fraction) number and multiply it by the denominator.
  3. Add that answer to the numerator.
  4. Put that amount over the original denominator and you will have an improper fraction.
Method for Adding and Subtracting Fractions:
  1. Find the lowest common denominator (bottom number). For both adding and subtracting fractions, you'll start with the same process.
  2. Multiply fractions to match the lowest common denominator.
  3. Add or subtract the two numerators (top number) but NOT the denominators.

Owens is 147.3 cm tall. What is Owens height as a mixed number? What is Owens height as an improper fraction?


4 feet and 10 inches MIXED (you just convert to feet and inches. http://www.miniwebtool.com/cm-to-feet-and-inches-converter/?cm=147.3

58/12 IMPROPER FRACTION
(10 inches is 10 parts of 12 as there are 12 inches to a foot. Each foot is 12 inches, so we multiply the 4 feet by 12, which makes 48, plus the 10 <inches> equals 58. As we are using12 as the divisor, it is 58 twelfths.

It is important that you are taught how to do this rather than just getting the answer :>)

What are improper fractions equal to 4 2/3?


I think of pizzas when doing fractions. If you cut the four full pizzas into thirds, how many slices will you have? Add this to the two other slices and you get your improper fraction.

So, to make an improper fraction, you multiply the whole number by the denominator and add it to the numerator. To get more improper fractions, you can multiply the numerator and denominator by the same number.

How can i change a mixed fraction to a improper fraction ?


Multiply the integer portion by the denominator of the fraction, add the numerator of the fraction, and put the result over the denominator.

If you're asking how to do this automatically on some calculator, what make and model?

What is a mixed number


That depends on the problem.
A mixed number is a number composed of an integer part and a proper fraction (fraction where the numerator is less than the denominator
A measure gives you 1 foot and 1/ 2 foot. Instead of writing 1.5 feet some people write 1 1/2. If you don't like mixed number you can convert them into improper fractions (fraction where the numerator is greater than the denominator.
1 1/2=1+1/2=(1*2+1)2=3/2
If you use them in a subtraction you should be careful because
7- 5 1/2=7-(5+1/2)=7-5 -1/2=2-1/2=(2*2-1)/2=3/2
You can multiply them, divide them, but any other operation quickly becomes ridiculously complicated. Some people like to use them. I don't much care for them.
In multiplication and division the general rule is to convert every number into its (reduced) improper fraction equivalent and then operate, using the rules for manipulating fractions.

Multiplying mixed fractions


Convert each mixed number (what you call mixed fraction) to an improper fraction, then multiply the two numerators and multiply the two denominators. Reduce the resulting fraction to its simplest form

Example
(2 1/3)*(1 5/7)=?
Convert 2 1/3 to an improper fraction 2 1/3=2+ 1/3 = 6/3+1/3=7/3
Convert 1 5/7 to an improper fraction 1 5/7=1+ 5/7 =7/7 +5/7=12/7
(2 1/3)*(1 5/7)= (7/3)*(12/7)= (7*12)/(3*7)
The 7's in the numerator and denominator cancel one another leaving
12/3=4
(2 1/3)*(1 5/7)=4
Not all products of mixed numbers will give a simple result as this one. More likely they will not.

How to divide mixed numbers?


Probably the simplest is to convert both numbers to improper fractions then divide.
Some calculators can work with fractions. With one of those, simply enter the first mixed number, then divide by the other.
