Section 1- reducing fractions, Part to whole fractions, part to whole fractions Section 2 -mixed numbers, Division and reciprocals with fractions, multiplication with fractions Section 3- Adding and Subtracting with fractions
First you need to find a common factor Then divide the numerator and the denominator by the common factor
Hannah had 4 dogs and Madison Erb has 6 dogs. Hannah has 4 black dogs and Madison Erb has 6 black dogs What is the reduced fraction of Madison’s and Hannah’s dogs?
Hannah- 4 black dogs 4/10 total dogs 4/10 divided by 2 (numerator and denominator) to get 2/5 Madison Erb- 6 black dogs 6/10 total dogs 6/10 divided by 2 (both numerator and denominator) 3/5
Fractions are part to whole because the denominator is the total. Also, is the same as a whole. The numerator is the part which is how many is out of the whole.
To make a mixed number you need to take an improper fraction and make it to a mixed number in these steps. First you need to, for example take 9/5 and you look at denominator and you have to see how many times it goes into the numerator. In this case it’s only 1 time. So you know 1 is the whole number but you don’t know the numerator or denominator. So you have a remainder of 4 so that will be your numerator. And 5 will still be your denominator. Therefore your mixed number is 2 4/5
Step 1. Multiply the numerators Step 2. Multiply the denominators Step 3. If needed simplify the fractions
1/3 2/5 2/15 First I multiplied the numerators which came to 2. Then I multiplied the denominators which came to 15 Then I looked and I couldn’t reduce. 2/5 ½ 2/10 1/5 First I multiplied the numerators which is 2 Then I multiplied the denominators to 10 Then I looked to see if I could reduce which I can reduce to 1/5 ( 2)
If Rihanna had 12 singles and 1 album and Pink had 14 singles and 2 albums how many albums and singles do they have together? 12/1 +14/1 = 26/2 First I added the singles (numerator) and the albums (denominator) to get 26 singles and 3 albums
Step 1. Make the denominator the same. Step 2. First subtract the numerators (put the answer over the same denominator.) Step 3. If needed simplify the fraction.
6/8-2/8=4/8 then simplify so 4/8 will change to ½ 5/6-7/12 First get common denominators 10/12 -7/12 Next subtract the numerators 10/12 - 7/12=3/12 Then simplify 3/12=1/4
