I have math fractions to add. I never went over these ,so please help.
7/8 + 3/4 + 15/24=
5/9 + 6/7= 4/5 + 11/15 + 17/30 =
1 7/8 + 2 11/16 =
You need to use a common denominator and equivalent fractions when adding or subtracting fractions.
The common denominator for 8, 4, and 24 is 24.
7/8 = 21/24
3/4 = 18/24
Add the numerators:
21/24 + 18/24 + 15/24 = 54/24 = 2 6/24 = 2 1/4
Oh ,ok thanks
You're welcome.

Sure, I can help you with adding fractions!
To add fractions, you need to find a common denominator. This is a number that is divisible by all the denominators in the fractions you want to add. Once you have a common denominator, you can add or subtract the numerators of the fractions and keep the denominator the same.
Let's go through each of the expressions you provided one by one:
1) 7/8 + 3/4 + 15/24:
First, let's find the least common denominator (LCD) for 8, 4, and 24. In this case, the LCD is 24.
Now, we need to rewrite each fraction so that they all have the same denominator, which is 24:
7/8 = 21/24 (multiply the numerator and denominator by 3)
3/4 = 18/24 (multiply the numerator and denominator by 6)
15/24 = 15/24 (already in terms of 24)
Now, we can add the fractions together by simply adding the numerators:
21/24 + 18/24 + 15/24 = (21 + 18 + 15) / 24 = 54/24
The fraction 54/24 can be simplified by finding the greatest common divisor (GCD) of 54 and 24, which is 6. Divide both the numerator and denominator by 6:
54/24 = (54 ÷ 6) / (24 ÷ 6) = 9/4
So, 7/8 + 3/4 + 15/24 equals 9/4.
2) 5/9 + 6/7:
To add these fractions, we need to find a common denominator. The least common denominator (LCD) for 9 and 7 is 63.
Rewrite each fraction with the denominator of 63:
5/9 = 35/63 (multiply the numerator and denominator by 7)
6/7 = 54/63 (multiply the numerator and denominator by 9)
Now, we can add the fractions:
35/63 + 54/63 = (35 + 54) / 63 = 89/63
The fraction 89/63 cannot be simplified further because the numerator and denominator do not have a common divisor other than 1.
So, 5/9 + 6/7 equals 89/63.
3) 4/5 + 11/15 + 17/30:
For this expression, let's find the least common denominator (LCD) for 5, 15, and 30, which is 30.
Now rewrite each fraction with the denominator of 30:
4/5 = 24/30 (multiply the numerator and denominator by 6)
11/15 = 22/30 (multiply the numerator and denominator by 2)
17/30 = 17/30 (already in terms of 30)
Add the fractions together:
24/30 + 22/30 + 17/30 = (24 + 22 + 17) / 30 = 63/30
The fraction 63/30 can be simplified by finding the greatest common divisor (GCD) of 63 and 30, which is 3. Divide both the numerator and denominator by 3:
63/30 = (63 ÷ 3) / (30 ÷ 3) = 21/10
Therefore, 4/5 + 11/15 + 17/30 equals 21/10.
4) 1 7/8 + 2 11/16:
When adding mixed numbers, you have to add the whole numbers separately and then add the fractions separately.
For the whole numbers:
1 + 2 = 3
For the fractions:
7/8 + 11/16
To add these fractions, we need to find a common denominator. The least common denominator (LCD) for 8 and 16 is 16.
Rewrite each fraction with the denominator of 16:
7/8 = 14/16 (multiply the numerator and denominator by 2)
11/16 = 11/16 (already in terms of 16)
Now, add the fractions together:
14/16 + 11/16 = (14 + 11) / 16 = 25/16
The fraction 25/16 can be written as a mixed number by dividing the numerator (25) by the denominator (16). The quotient is the whole number, and the remainder becomes the numerator of the fractional part:
25 ÷ 16 = 1 remainder 9
Therefore, 1 7/8 + 2 11/16 equals 3 9/16.
I hope these explanations help you understand how to add fractions! Let me know if you have any further questions.
