Improper Fractions to Mixed numbers, Mixed numbers to improper fractions.
Changing a Mixed Number into an improper fraction
There are 2 1/2 kiwis left in the fridge. How many halves are there?
You need to multiply the whole number (2) and the denominator (2) and then add the numerator (1) and then you get the product(5). You keep the denominator the same and make it an improper fraction. So, you're answer would be 5/4.
There are 4 whole bananas and 1 banana that is cut into 6 pieces. If every banana is cut into 6 pieces, how many pieces are there?
You take 4 1/6 and multiply the whole number (4) and the denominator (6). And then you add the numerator (1) and get the answer of (25). You keep the denominator the same so your final fraction would be 25/6.
Improper to mixed numbers, Mixed numbers to improper fractions
There are 4 and 1/4 pies. If each pie is cut into 4 pieces, than how many pieces of pie are there?
You multiply the whole number (4) and the denominator (4) and then add the numerator (1) which you would get the final fraction of 15/4.
There are 7 dogs with 3 in each group. How many groups are there and how many dogs are there without a group?
7/3- divide 7 by 3 and you will get 2 and a reaminder of 1. So, your final fraction woud be 2 1/3.
If there are 15 Hersey pieces and there are 7 in a group, then how many groups and leftovers would there be?
15/7 if you divide 15 by 7, you would get 2 with a remainder of 1. So, your final fraction would be 2 1/7.
Improper fractions to mixed numbers
Okay, now onto turning improper fractions into mixed numbers. You take the denominator and divide it by the numerator. for example, 9/4 would be 9 divided by 4 and you would get 2 1/4.
There are 19 cats with 4 in each group. How many groups are there and how many cats are there without a group?
19/4- Divide 19 by 4 and you get 4 and 3 as your remainder. You use your remainder as the numerator in your final fraction. So, your final mixed number would be 4 3/4.
To change a Mixed Number into an improper fraction, you would multiply the whole number by the denominator and then add your numerator to the product. That number goes as the numerator and the denominator stays the same(unless you can simplify)
There are 2 5/8 pizzas left after a party. How many slices are there? Multiply the whole number (2) and the denominator (8) and then add the numerator (5) and get the final fraction of 21/8.
A baker made 34 doughnuts and 12 have to go into 1 box. How many boxes will he have and how many doughnuts will be left over?
12/34. Divide 12 by 34 and you will get 2 10/12. (DON'T FORGET TO SIMPLIFY IF POSSIBLE) So simplified, it would be 2 5/6.
