How do you write 3 equivalent fractions for 4 over 9?
Equivalent fractions are numbers with the same value as 4/9. One example is 8/18, another is 2/4.5
What is 9 and two thirds plus 2 and seven ninths?
Convert 2/3 to 6/9, then you can add the whole parts, and add the fractions, you will have: (9 + 2) + (6/9 + 7/9) = 11 + 13/9. 13/9 is the same as 1 4/9, so then you have 124/9.
What is the rule in adding fractions having the same denominator?
Sum of the fractions = sum of numerators divided by their common denominator. Adding Fractions rule implies to addition of fractions having same denominator and as well as adding fractions with different denominators. So rule for adding fractions having the same denominator is add the numerators and simplify For example : 3/5 + 2/5 + 9/5 = (3 + 2 + 9)/5 [add the numerators] = 14/5
How do you add fractions and subtract similar and dissimilar fractions?
If the fractions have the same denominator, you can add and subtract them by adding or subtracting the numerator. For instance 2/7 + 3/7 = 5/7 Or 7/9 - 2/9 = 5/9 When the denominators are not the same, you need to multiply both top and bottom of the fractions until the denominators are the same. For instance, if we wanted to do 1/3 + 2/9, we would need to first multiply top and bottom of the first fraction by 3, which makes the question 3/9 + 2/9. Once the denominators are the same, the subtraction or addition can be completed as outlined in the first paragraph.

How do you add and subtract mixed numbers?
SUBTRACTION: You first turn both mixed numbers into improper fractions. If needed, change the denominators into like denominators. Next, subtract the two improper fractions and reduce if necessary. ADDITION: If needed, turn denominators so they are the same number. Next, add and reduce if necessary.
How can you make 9 with 8different numbers?
0 + 9 = 9 1 + 8 = 9 2 + 7 = 9 3 + 6 = 9 You can also, of course, use fractions and negative numbers.
1 over 9 plus 4 over 9?
If you are using the word "over" to describe that these numbers are fractions, then 1/9 plus 4/9 is 5/9. Since the denominators are the same, you simply add the numerators of both fractions, and you have your answer, 5 over 9.
