Why decimals greater than 1 become improper fractions when converted?
When you convert a decimal greater than 1 into a fraction its easier to change it into a mixed number first. Then change it into an improper fraction.
Do you change a mixed number into an improper number while adding and subtracting?
you do what makes sense given the numbers, if the fractions work out beautifully, you can just leave them as mixed numbers, otherwise it's best to keep them as improper fractions
What is a improper fractions?
An improper fraction is when the numerator is a greater sum then the denominator. Example- 10/5. To change that into a proper fraction you divide the numerator by the denominator. Example - 2 1/5
How do you multiply improper fractions with simple fractions?
Multiply the numerator by the numerator, and the denominator by the denominator. If you find this explanation unclear, take this example: 9/8 (improper fraction) x 3/4 (simple fraction) = 27/32 (answer)---if you can simplify it, do so. If it is a mixed number (e.g. 1 3/4), change the mixed number to an improper fraction and follow the steps above. The same applies to simple fraction multiplying by simple fraction.
What are improper fractions?
An improper fraction is a fraction with the numerator (the top number) being higher than the denominator (the bottom number). For example, 13/5 is an improper fraction because the top number is greater than the bottom number. To change it to a mixed number (which is a number with a fraction and a whole number), you divide the numerator by the denominator, which = 23/5
